Sometimes I think about lasts. I can list a few that have already come and gone: last mountain I hiked, last time I rode a bike, last time I played golf or shot pool or lifted both arms over my head. There are of course countless more that may have already passed me by. Most people may be comforted by the idea that they could do all of those things again, though in reality many of them may have been left behind. I know that many of them are gone, and I fear that there are many more than I am willing to admit.
