In my younger days, I always loved working on stuff. i.e. my bikes, cars, the house, appliances, etc. Then after 30+ years of repairing machinery for my job, I just don't enjoy repairing things, anymore. I've been retired for over 10 years and I still never got the love back. I basically do only what is necessary to keep everthing operating properly.

I also find things take me a lot longer, now. I used to be able to strip and entire bike, clean all the parts and reassemble it in a day. Now, it takes a week (if I'm lucky).
