i work from home so i do usually. once you get good at cooking, most restaurant food is un-appetizing or extremely expensive for what you are receiving. it also helps me maintain my weight and not be a complete fatass.
i still eat out a couple of times a week but i'd say a good 75% to 90% of my meals are cooked at home. par-cooking common ingredients in batches helps a lot. it's basically like running a small commercial kitchen for myself.
once you get good at cooking it's basically a 'flow' activity. line cooks get 'in the zone' when the rush hits.
also, once you get the basics down most day to day meals take about 10-15 minutes to cook, not including roasting time which is passive.
the only downside for cooking to me is the cleanup. that never stops sucking for me and brings out my lazy streak.
People with children at home will obviously have very different time allocations (I do laundry almost daily, and if I let it pile up to fold once a week it takes 2-3hours to fold and put away everything. Family meal times can take 2hours each, depending whether we get the food ready quickly and the kids feel like eating. Someone is always sick. )
People who enjoy cooking, and people who actually care for their health.
I make five medium sized breakfast burrito's on Sunday night and refrigerate them. One every morning. That's a whole wheat wrap, a couple eggs, green peppers, and chopped onions. This takes me about a half hour on Sunday including cleanup and 5 seconds to grab one out of the fridge each morning. I supplement it with a granola bar.
I won't claim to be ultra concerned with my dietary balance, but you definitely don't need to spend a ton of time cooking to be healthy.
If it tasted better, I might still be doing it. It's actually the same sort of thing prisons feed to problem inmates to punish misbehavior, except they call it "nutriloaf", and put more actual food in it.
Mine was mostly eggs, coconut oil, and chia seed. It looked horrible, but it barely tasted like anything at all. I might tweak my recipe and try it again some day, but the family won't even look in its general direction, so somebody still has to actually cook meals.
I'll have my wok cleaned and put away for next time before the frozen pizza chefs have their oven preheated. Or I'll be half done eating my lunch salad before the frozen burrito comes out of the microwave.
I'm not sure that "open bag, dump salad on plate" even counts as cooking, but that's like 1/3 of my meals and the "cooking" process takes about 10 seconds.
I don't have orthopedic problems, but I've found that I'm generally more comfortable by the end of the day if I'm wearing shoes at home vs barefoot or slippers. This is especially true if I spend a few hours in the kitchen standing up to cook, etc.
Additionally, where I grew up it's odd/rude for a visitor to remove their shoes or be asked to remove their shoes. Different strokes and all that. :)
1. Work: 40 hours
2. Cooking: 3 h (who the hell cooks three times a day?)
3. Laundry: 0.5 h (once a week)
4. Cleaning: 1 h (and I am very clean, I just avoid producing dirt)

6. Bills: 0 h (they a are paid automatically from my account)

8. Transport: 4 h (I ride my bicycle to work, so one could count that as exercise)
9. Staying healthy: 4 h (in addition to the bicycling to and from work)
10. Finances: 0 h (I have no idea how anyone can spend so much time on this. I just live by the simple rule: don't get into debt and move some of your income automatically on a saving account)

I think it all comes down to priorities and you current life situation. But one can influence most of these things and you have to decide what is really important in your life. For me, it's free time.
