I want to take the granularity down a notch. For everything you do, there is a last time you do it: ride a bike, make a new friend, visit Italy, hike a mountain, write code, see the sea, watch Shakespeare, see your mother, post to HN, play tennis, hug your grandchild, eat tiramisu, listen to Miles, have sex, walk without pain, remember your first love, drink a beer, take a breath. Some are already in your past, you may not know which ones. The rest are in your future of unknown duration. They will each pass without fanfare, mostly without you noticing. Like crossing the event horizon of a large black hole: there is no going back, but you may not know it at the time. I suspect, for me, the last two on my list will be quite close together.
