Recognizing aging

Signs that I have aged besides wrinkles and receding hairline:

1. Harder to adjust to jet lag. I used to be able to adapt to the different time zone quickly. Nowadays, I needed at least three days for my biological clock to be in tuned with the time zone.

2. My legs actually felt numb during my long 27-hour of flight.

3. My sense of balance is affected.

4. Tight tendons. I had to stretch my muscles in-between running to prevent aching.

5. Lower metabolism where I put on weight if I do not exercise enough.

After a month of indulging in gluttony in Singapore, I weighed 80.6kg. Since returning, my eating habit resumed to normal and I went to the gym daily, alternating between running and lifting weights. Currently, my weight was 79kg.
