Can feel the difference...

Can really feel the difference between then and now...

I used to be able to stay up late for several days/weeks and recover fast by sleeping one, or the most, two days, but now, aiy.... If I stayed up late for more than 3 nights in a row, I can really feel the effect of those late nights on the 4th day. I need to sleep and rest for at least 2 - 3 days to recover from those late nights.

And I also realised that I tend to get sick fairly easily these days... Hopefully, with my new mattress, soon my back will feel good enough for me to start jogging... I must build up my health and stamina, can't keep falling sick...
