I think the amount of sleep the average person actually needs does depend on each individual...I sleep about 6.25 hours a night on average and that is all I need..tht adds up though over the course of an adult lifetime.
Avg person 9 hours for 60 adult years.
6.25 hours of sleep average for 60 adult years.
In this example your getting an extra 24 hours of awake time every 10 days of your life.
10 full days year...and 600 more days awake in a lifetime on average...almost 2 full years you can save just by being less of a sleep head, of course 95% of gamblers sleep less than avg anyway.
