I’m 51. The biggest surprise so far was that my body kind of gave up alcohol without asking me. I always was a lightweight, but really enjoyed a drink when I had one. Now mostly alcohol gives me a headache and fatigue to the point that I’ve become conditioned to avoid it. This was a slow change, probably started in my early 40s. I kind of miss the quick path to pleasure that a drink offered, but I suppose this problem is better than the opposite.
My left knee kind of fell apart at age 48. This was not a huge surprise because my knees had been aching for years, but it is sad to have gone from someone who even in my early 40s would dash up stairs and scramble up rocks and balance on logs to someone who can’t do any of those things and has to be much more deliberate and measured about movement. I’ve actually had a great recovery from the initial decomposition but I’m not the same as before. One day I might have a knee replacement, but I’ve been told to put it off as long as possible.
My sex drive skyrocketed after 40 though this may have less to do with age and more to do with my kids getting old enough for me to get enough sleep regularly.
I have also been surprised that the future has arrived and seems slightly less terrible than any dystopian imagining of my youthful sci-fi consumption, but also far more ridiculous. Basically the science fiction visionary has proved to be Mike Judge in creating Idiocracy and that is too bad. I figured by now I would be living in a nuclear wasteland, so this is…better…probably??
