Old Age

After working for Dr Lau who's 80+ this year, I realised for the first time that I am so afraid of growing old.
I'm 19 this year, already i am feeling so old as compared to those nubile young things I see on the streets.
Then i look at those aunties in my neighbourhood with those saggy bits hanging around, some of them are balding. Yes, balding middle aged women are such turn-offs.
Then I think about myself:
I havent been exercising due to laziness and asthma for a few years already.
I've never made an effort to eat healthily.
My skin is bad.
Though not obese, I am overweight.
How can I dream of being still healthy when I grow old?
Especially when I've seen so many 邓萃雯 shows when people keeps repeating how woman lose their value once they are old:
女人老得太快，智慧来得太迟。
减得了身形，也减不了年龄。
etc
I am so so afraid of becoming an obese old spinster on wheelchair and little hair on my scalp.
OMG...
