Speaking for myself, there are two trends with aging. One positive, one negative.
1. (positive) Big picture wisdom increases. You learn when to call in help, when to use a library instead of rolling it yourself, when to stop hacking, retreat, document, how long to architect, etc. I get a little frustrated with younger people who e.g. over-optimize some aspect of a system before making the whole thing work adequately. I am waaaaaaay more organized and consistent than the young person who hasn't inherited enough code or faced the spectre of their own code when they forgot how it works.
2. (negative) I often forget how easy some formerly difficult tasks have become. Just take a library like three.js.... or building a compiler from source or using a library instead of writing an XML parser or SDL and so on. To stay on top, I often have to check in with others to see what surprising tools "young people" :) have made. This is critical because it affects estimates of time and resources needed to meet a goal.
So it's excellent to be around for a long time, IMO, as long as you are good at forgetting/unlearning some obsolete ways of doing things.
