I honestly wish I never had to retire.
Not from the regular work I do now, but from those tasks I love doing and now do not have as much time as I wish.
One thing I love is the ocean of information you can find on the internet nowadays to learn new stuff and try it yourself. Coding, cooking, wood construction, gardening.....and biking!!!, yes, maybe I will have to get an e-bike as I get old but at least I will still be able to bike :)
I am sure I will be quite busy and cant wait to reach that point!
I feel I would never get to, but I know what you mean! There is so many things that can be done :)
