Age Sleep

It is crazy to ponder that when I was younger I needed at least 8-10 hours of sleep to barely function. Aren't younger people supposed to have more natural energy? Well, now that I'm older all I need is 3 hours of sleep and I'm good to go, I feel energized, alert, and on the move and ready to take on the world....well maybe not the world, FTW, at least ready for the day so yeah IDK, it is what it is people.
