1
00:00:00.100 --> 00:00:03.144
First of all, our definition of

2
00:00:03.144 --> 00:00:04.127
aging is different.

3
00:00:04.131 --> 00:00:06.080
(What is the standard for being old!?) 
Young people look at ***,

4
00:00:06.080 --> 00:00:08.808
while older people look at ***.

5
00:00:08.808 --> 00:00:12.339
When speaking from a young person's perspective, *** is essential!

6
00:00:13.900 --> 00:00:16.601
(Speechless) 
PD: Dr.Lee, now that I'm in my 30s, I feel so tired

7
00:00:16.601 --> 00:00:18.311
and it seems like my face is sagging.

8
00:00:18.311 --> 00:00:19.543
Isn't this too much?

9
00:00:19.544 --> 00:00:20.345
Right in front of me?!

10
00:00:20.346 --> 00:00:21.716
(Oh, come on)

11
00:00:21.717 --> 00:00:23.096
Just because you've entered your 30s...

12
00:00:23.399 --> 00:00:25.367
(Angry) 
I can't even speak, I'm so frustrated.

13
00:00:25.367 --> 00:00:26.507
Why do humans age...

14
00:00:26.508 --> 00:00:27.679
Can't we stop aging?

15
00:00:27.681 --> 00:00:29.378
You can stop aging!

16
00:00:29.380 --> 00:00:31.537
How great would it be if I could say that?

17
00:00:31.538 --> 00:00:33.310
I would love to know the answer too.

18
00:00:33.310 --> 00:00:34.889
While we can't completely stop aging,

19
00:00:34.890 --> 00:00:37.316
can't we at least slow it down?

20
00:00:37.336 --> 00:00:40.119
(Dr. Lee, Jfeel Clinic)
Hello, I'm Dr. Lee, pursuing the most beautiful aesthetic.

21
00:00:40.119 --> 00:00:41.914
Aging.

22
00:00:41.915 --> 00:00:44.448
The word itself carries weight.

23
00:00:44.448 --> 00:00:46.673
So, what is aging?

24
00:00:46.905 --> 00:00:52.340
It is the process in which the body and mind change over time, and functions decline.

25
00:00:52.340 --> 00:00:55.042
It’s not just about external appearance,

26
00:00:55.042 --> 00:00:57.002
it also involves the gradual deterioration of

27
00:00:57.003 --> 00:00:58.487
cells, tissues, organs,

28
00:00:58.487 --> 00:01:00.320
and physiological functions.

29
00:01:00.320 --> 00:01:01.959
So, when does aging start?

30
00:01:01.959 --> 00:01:04.576
(Aging, how can we delay it?)
And how can we slow it down?

31
00:01:04.576 --> 00:01:09.601
We often think that we age gradually and consistently each year

32
00:01:09.601 --> 00:01:11.382
but that’s actually not the case.

33
00:01:11.382 --> 00:01:12.895
A new study on human aging

34
00:01:12.896 --> 00:01:14.878
has been proposed

35
00:01:14.886 --> 00:01:16.639
which caused a huge stir.

36
00:01:16.639 --> 00:01:19.226
It suggests that rather than aging at a consistent,

37
00:01:19.226 --> 00:01:22.239
and gradual pace every year,

38
00:01:22.493 --> 00:01:25.760
humans experience three significant aging jumps.

39
00:01:25.760 --> 00:01:31.516
Researchers analyzed plasma from the blood of 4,263 people aged 18 to 95

40
00:01:31.516 --> 00:01:33.805
and discovered that the levels of certain proteins

41
00:01:33.805 --> 00:01:36.392
noticeably increased with aging.

42
00:01:36.400 --> 00:01:39.075
The most striking periods of rapid change

43
00:01:39.076 --> 00:01:43.507
occur at 34, 60, and 78 years old.

44
00:01:43.507 --> 00:01:49.800
So, does that mean we only need to be cautious at 34, 60, and 78?

45
00:01:49.800 --> 00:01:54.800
Honestly, I think it's more likely that aging accumulates over time 
and then manifests suddenly at those ages.

46
00:01:54.800 --> 00:01:57.239
Of course, the progression of aging varies from person to person.

47
00:01:57.265 --> 00:02:02.599
But generally, aging is considered to begin in the late 20s to early 30s.

48
00:02:02.599 --> 00:02:05.722
Aging is caused by various biological factors

49
00:02:05.723 --> 00:02:07.979
interacting in complex ways.

50
00:02:07.980 --> 00:02:10.880
One of these is cellular and genetic factors.

51
00:02:10.880 --> 00:02:14.320
Shortening telomeres, damage to DNA, and so on.

52
00:02:14.320 --> 00:02:16.611
And it accumulates damage to your body.

53
00:02:16.611 --> 00:02:17.952
It's called active oxygen these days.

54
00:02:17.952 --> 00:02:19.999
Or protein modification

55
00:02:20.000 --> 00:02:23.520
and the mitochondrial function in the cell decreases.

56
00:02:23.520 --> 00:02:24.566
As time goes by,

57
00:02:24.567 --> 00:02:27.018
our body uses energy inefficiently.

58
00:02:27.019 --> 00:02:30.864
And environmental factors and lifestyle may be the cause.

59
00:02:30.864 --> 00:02:32.527
It's complicated, but

60
00:02:32.527 --> 00:02:33.858
as we get older,

61
00:02:33.858 --> 00:02:35.583
it means that aging comes with it.

62
00:02:35.583 --> 00:02:37.701
The factors that affect the rate of aging are

63
00:02:37.702 --> 00:02:40.377
20 to 30% of genetic factors.

64
00:02:40.401 --> 00:02:42.960
Everything else depends on the lifestyle.

65
00:02:42.960 --> 00:02:44.714
Exercise, nutrition,

66
00:02:44.715 --> 00:02:46.133
alcohol, cigarettes, UV rays,

67
00:02:46.136 --> 00:02:49.820
stress, and sleep is also an issue these days.

68
00:02:49.820 --> 00:02:51.170
If that's the case,

69
00:02:51.171 --> 00:02:53.779
is there any way to slow down the aging rate?

70
00:02:53.779 --> 00:02:55.596
It's helpful to eat antioxidant food,

71
00:02:55.597 --> 00:02:56.874
(Steady work out)
work out consistently,

72
00:02:56.874 --> 00:02:59.039
(Enough sleep)
sleep for 7 to 9 hours,

73
00:02:59.039 --> 00:03:00.766
(Relieving stress)
reduce stress,

74
00:03:00.766 --> 00:03:03.901
and maintain healthy relationships.

75
00:03:03.901 --> 00:03:08.664
After all, ways to slow down aging is in line with how to live a healthy life.

76
00:03:08.664 --> 00:03:09.898
Dr.Lee, what do you think

77
00:03:09.899 --> 00:03:11.705
is the most important part?

78
00:03:11.722 --> 00:03:13.714
I think it's sleeping.

79
00:03:13.717 --> 00:03:17.013
Fortunately, I look younger than my actual age.

80
00:03:17.017 --> 00:03:18.670
I sleep a lot.

81
00:03:18.670 --> 00:03:21.567
I always sleep for more than 7 hours.

82
00:03:21.567 --> 00:03:23.155
(The secret of Dr.Lee to being young is sleeping)
I usually sleep for 9 hours.

83
00:03:23.161 --> 00:03:26.247
While we sleep, we don't get stressed out,

84
00:03:26.247 --> 00:03:27.797
we don't get any UV rays, either.

85
00:03:27.798 --> 00:03:29.992
If you sleep a lot, you'll have less time to drink,

86
00:03:29.992 --> 00:03:31.914
less time to smoke.

87
00:03:31.914 --> 00:03:33.212
How good is that?

88
00:03:33.212 --> 00:03:34.654
If there's a disadvantage,

89
00:03:34.655 --> 00:03:35.622
since I sleep a lot

90
00:03:35.622 --> 00:03:37.111
I don't have time to work out.

91
00:03:37.111 --> 00:03:39.868
I'm running around in the hospital

92
00:03:39.868 --> 00:03:41.809
to meet you instead of working out.

93
00:03:41.843 --> 00:03:43.912
What about things you think that fastens aging, if we don't do it?

94
00:03:43.912 --> 00:03:46.824
First of all, our definition of

95
00:03:46.825 --> 00:03:47.988
aging is different.

96
00:03:47.988 --> 00:03:50.219
(What is the standard for being old!?) 
Young people look at appearance,

97
00:03:50.219 --> 00:03:52.479
while older people look at cognitive abilities.

98
00:03:52.479 --> 00:03:54.240
(If you're young, sunscreen)
When speaking from a young person's perspective,

99
00:03:54.240 --> 00:03:57.254
sunscreen is essential!

100
00:03:57.254 --> 00:03:59.016
If you don't use sunscreen,

101
00:03:59.016 --> 00:04:01.945
at some point, your skin suddenly ages drastically due to photoaging.

102
00:04:01.945 --> 00:04:03.480
In case of elderlies,

103
00:04:03.480 --> 00:04:04.823
when it comes to cognitive function,

104
00:04:04.824 --> 00:04:08.711
I recommend never stopping the challenge of learning new things.

105
00:04:08.711 --> 00:04:10.898
People say that exercising regularly helps you stay young.

106
00:04:10.898 --> 00:04:12.919
But if you see someone who exercises excessively,

107
00:04:12.919 --> 00:04:13.960
they actually show signs of aging.

108
00:04:13.960 --> 00:04:16.276
Excessive exercise that doesn't suit your body

109
00:04:16.276 --> 00:04:18.393
only causes joint pain and has no real benefits.

110
00:04:18.396 --> 00:04:20.602
Adequate exercise is ideal,

111
00:04:20.602 --> 00:04:22.128
but that’s always the tricky part.

112
00:04:22.128 --> 00:04:23.808
Adequate food intake,

113
00:04:23.808 --> 00:04:25.073
adequate exercise,

114
00:04:25.073 --> 00:04:26.160
and adequate sleep.

115
00:04:26.160 --> 00:04:26.799
People always talk about these things.

116
00:04:26.799 --> 00:04:29.600
(Adequte differently from each person)
But the definition of "adequate" varies greatly from people to people.

117
00:04:29.600 --> 00:04:31.871
In other words, no one really knows the exact answer.

118
00:04:31.871 --> 00:04:34.136
If someone feels completely refreshed after just five hours of sleep,

119
00:04:34.136 --> 00:04:36.320
then five might be the right amount for them.

120
00:04:36.320 --> 00:04:39.284
(Point is to find what works best for your own body) 
I think it is important to find what works best for you.

121
00:04:40.354 --> 00:04:42.708
(Shh! This is just between us)

122
00:04:42.708 --> 00:04:45.058
Since I work in the skincare field,

123
00:04:45.060 --> 00:04:47.456
let me explain a bit about skin.

124
00:04:47.456 --> 00:04:50.679
One of the biggest concerns in skin aging is the loss of elasticity.

125
00:04:50.679 --> 00:04:52.968
In other words, sagging skin.

126
00:04:52.968 --> 00:04:54.659
First, unfortunately,

127
00:04:54.660 --> 00:04:56.533
('This' accelerates skin sagging? 1.Genetics) 
Genetics plays the biggest role.

128
00:04:56.533 --> 00:04:57.770
It’s the natural elasticity you’re born with.

129
00:04:57.770 --> 00:04:59.347
The thinner and stretchable your skin is,

130
00:04:59.348 --> 00:05:00.671
the more likely it is to lose elasticity.

131
00:05:00.671 --> 00:05:02.667
('This' accelerates skin sagging? 2.Gravity)  
The second factor is gravity.

132
00:05:02.667 --> 00:05:03.718
If you have more facial fat,

133
00:05:03.719 --> 00:05:06.292
you may be more affected by gravity.

134
00:05:06.292 --> 00:05:08.163
PD : So does that mean losing weight prevents sagging?

135
00:05:08.163 --> 00:05:09.526
Not necessarily.

136
00:05:09.526 --> 00:05:12.546
In fact, people who repeatedly gain and lose weight

137
00:05:12.548 --> 00:05:13.927
tend to experience more skin sagging.

138
00:05:13.935 --> 00:05:16.022
Think of a deflated balloon.

139
00:05:16.027 --> 00:05:17.945
A balloon that was once tight,

140
00:05:17.945 --> 00:05:20.130
what happens if you inflate it fully and then release the air?

141
00:05:20.130 --> 00:05:21.359
It becomes wrinkled.

142
00:05:21.359 --> 00:05:23.120
If your skin’s elasticity can’t keep up

143
00:05:23.120 --> 00:05:24.430
and simply lose weight,

144
00:05:24.431 --> 00:05:25.681
it won’t give you the desired look

145
00:05:25.681 --> 00:05:27.648
and instead, make the sagging even worse.

146
00:05:27.654 --> 00:05:30.760
In this case, I recommend treatments that boost skin elasticity.

147
00:05:30.760 --> 00:05:33.271
And unfortunately, for women,

148
00:05:33.274 --> 00:05:36.200
('This' accelerates skin sagging? 3.Menopause) 
Menopause is another major factor that contributes to skin sagging.

149
00:05:36.200 --> 00:05:37.992
Within the first five years after menopause,

150
00:05:37.992 --> 00:05:42.399
studies have shown that skin collagen decreases by about 30% drastically.

151
00:05:42.399 --> 00:05:44.473
('This' accelerates skin sagging? 4. Environment) 
And there is an environmental factor.

152
00:05:44.473 --> 00:05:46.332
UV rays, dryness, lack of sleep,

153
00:05:46.333 --> 00:05:49.198
stress, smoking, drinking, and sugar intake are some of them.

154
00:05:49.201 --> 00:05:50.957
As for environmental factors,

155
00:05:50.957 --> 00:05:53.421
if you try your best to eat well, sleep well, and apply well,

156
00:05:53.421 --> 00:05:55.481
you can slow down the skin sagging to some extent.

157
00:05:55.481 --> 00:05:58.096
But at some point, lifestyle changes and prevention alone

158
00:05:58.096 --> 00:05:59.308
won’t be enough.

159
00:05:59.308 --> 00:06:02.519
At this point, professional treatments can help.

160
00:06:02.519 --> 00:06:05.920
High-frequency and ultrasound procedures,

161
00:06:05.920 --> 00:06:08.079
collagen skin boosters,

162
00:06:08.079 --> 00:06:11.040
or laser lifting

163
00:06:11.040 --> 00:06:12.640
can improve skin elasticity

164
00:06:12.640 --> 00:06:16.239
and regenerate lost collagen.

165
00:06:16.239 --> 00:06:18.601
Today, we talked about aging. How was it?

166
00:06:18.601 --> 00:06:20.129
Aging is a natural process

167
00:06:20.130 --> 00:06:22.493
that everyone goes through,

168
00:06:22.509 --> 00:06:24.343
but with good lifestyle habits,

169
00:06:24.343 --> 00:06:27.720
you can maintain a healthy and vibrant life for longer.

170
00:06:27.720 --> 00:06:29.635
Slowing down aging

171
00:06:29.635 --> 00:06:33.600
is essentially about enhancing your quality of life.

172
00:06:33.600 --> 00:06:37.279
