But there you use the word 'need'. If you have been working 48 hours straight and want to hire the neighbors kid to mow the lawn that's now a foot high, fine.
It's just my viewpoint, I know how much time I waste (heck I'm wasting it right now) and how much time I have to take care of the lawn, etc. I don't need to add to the waste because I don't feel like doing it.
If you don't do anything physical at work then raking leaves might actually be good for you. It's exercise, fresh air and I find these kind of chores somewhat tranquillising to the mind. Same with other chores, but I'm sure there are ones I hate more than others. If there are physiological and psychological benefits of doing these chores, then it might be costing you more than the $10/hr of hiring someone else to do them. Sure you might be able to get some of the benefits by say going to the gym, but paying someone to do your gardening while you go to the gym to get the exercise you missed from doing the gardening seems a bit insane.
