The Ultimate Purpose of Life (1)

I aim to live till 80 years old :D

80 * 365 = 29200 days to be exact.

means i got 29200 days for my life.... sounds very short.

i'm 22years old + 5 months = 8180 days ald passed.

remaining around 21000. (^.^)

21000+

so what can i do to utilize these 21000+ days ?
