For a lot of people, finding the time to do either (let alone the financial outlay) is impossible.
You want to tell single parent working two jobs in an apartment that's moldy to "try playing golf. Read more!"?
my hobbies included waking and running around, making stuff on an old laptop (I kept that one!), reading, making planes out of whatever material i could get my hands on that sort of stuff. i ate pasta, eggs, rice, water, tomatos. i never cared about eating the same thing everyday (i still don't but ive learned to eat a little better).
theres plenty more hobbies, obviously none of these being forbidden in the USA lol. and most make more money than I did, not to mention have food stamps and the like.
