Interesting topic. While your senses may or may not be what they used to be, judging is a subjective thing. Also, you are retired and have the free time to pursue this. Free time is the biggest barrier for myself and many others, so don’t take that for granted.
Most importantly, if going through the process will bring you joy, do it. If you see the requirements as a burden, don’t. It should be all about fun, learning, and personal growth.
Cheers!
