I experience this too where I find it hard to motivate myself as I get older. So I stay clear of activities which I used to be my biggest hobbies, either because of fear to my health (snowboarding, ultra marathons, etc) or because my mind ages which is the hardest fight of it all because it all starts with attitude. Spotting that behavior in myself is the hardest thing of all. So easy to see it in my friends but am totally blind to my own idiotic old-man behavior. Thanks nuduerme for the delightful discussion. It's always nice to bump into like-minded "travelers" like yourself :)
