Strength needed for positive lifestyle changes

I have never considered myself a "crispy skin youngster" or thought of myself as weak physically. I work out daily even when I get a cold or sprain my ankle. Ice cream is a staple in my diet all year around and is a must after a spicy hotpot feast.

But after turning 30 last year, I began feeling signs of aging, or cracks in my iron crust.

The most tangible change lies in my sleep quality. I used to sleep like a log. On weekends, I could sleep for more than 15 hours a day to make up for all-nighters I pulled on weekdays to meet assignment deadlines and feel refreshed on Monday.
