I don't have any issues with sleeping, except sometimes when it's summer and it is too hot (for me at least) i can't get to sleep easily. But, 99. percent of the time i can sleep anywhere, anytime and even if i'm not tired.
I just woke up from a three hour "nap."
Also if need be, i can go long without sleep (i was an MP in the Rangers). Now i mostly do night shifts at work (high end security work).
Recently a friend of mine asked: "how can you sleep so much?"
I replied: "it is possible, because of my attitude, i'm so arrogant that i feel that i'm doing something extremely important, just because i eat and lift, most of the time"...
That conversation ended with laughing...
