TIME CONSUMED(WASTED) IN HUMAN SLEEP, BE AWARE..!!

Found this interesting article on net,

If someone stay alive for 70 years and sleeps daily for

1) 6 hours: spends 17.5 years of his life in Sleep state.
2) 8 hours: spends 23.3 years of his life in Sleep state.
3) 9 hours: spends 26.31 years of his life in Sleep state.
4) 10 hours: spends 29.1 years of his life in Sleep state.

Next time someone complaining not sleeping give this figures, now we have all reason to wake up late..!!!
