Sleep

A human spent on average 8 hours sleeping a day . [ if you want to why human have to sleep go and read my series discussion theory around the world ] if a human sleep 8 hours a day which mean 56 hours a week . Which also mean if you sleep 8 hours a day so , you will sleep 240 hours a month or 10 days of month. 365 multiple by 8 hours so answer will be 2920 hours or 121.666666666666 days . I am not going to multiple 65 years into 8 hours because it is one-third of human beings life . So i am late and i am feeling sleepy good night or good morning.
