What's going on between the ears is of particular interest. I have a suspicion that you might be slightly bonkers but your mental discipline is quite remarkable.
Ha,ha. I must admit I wonder myself at times. Why can't I be satisfied with what is considered a normal schedule. Well I doubt I would get more out of it than I already do, and I love setting off early and walking into the sunrise. Once the sun is up, it's too late, ive missed the best part of the day. Setting off early means that on a 'normal' schedule, I'd be finished before lunch, so I just keep going and the miles add up. Try it sometime.
