Overall, some folks love repairing old broken stuff (or need to due to financial circumstances). Most of us, our life satisfaction lies very much elsewhere and to spend our valuable remaining free time to just to learn properly and maintain such stuff that doesn't matter much in long run seems... unwise. Investing into relationships and intense experiences work generally better here.
I see plenty of older folks who maintain their houses and garden around themselves (I mean proper gardens with fruits and veggies etc, not those uniform fugly mandatory US lawns). It takes so much of their energy that they have little time nor energy for some other serious hobbies, travel etc. Eventually in old age they can't keep up and its extremely depressing for them, since their effort is usually lost to their kids and they just get rid of that ol' house.
