As I’ve grown older I’ve tended to go to bed later and get up later though not requiring so much sleep in between. In comparison, when younger, I was always up with the lark and most mornings would go for a 10k run before work. That set me up for the day, with my body on auto-pilot I could think clearly, planning my day or working out some complicated plot for a piece I was writing. It was quite a contrast being on a commuter train later along with blurry eyed passengers who looked like they could nod off at the drop of a hat while I sat bright eyed and bushy tailed full of energy and raring to go. I also had some of my best sex first thing in the morning, never failing to wake up with a woodie. I still get the woodie, but most times my wife has gone to work before I wake up!
