I voted for more than 60, because that's what's realistic to me. As my ex used to say I , "never stop working - never." Maybe I'm wrong but this 40-hour work week stuff seems to have started with the industrial age because
many of the jobs became factory type, do this for eight hours, tasks. Go way back and it was people farming their own land, building stuff one at a time - by hand, etc. People probably also tended to love what they were doing more, and gained a better sense of self-worth, satisfaction, and contentment, from it, so there wasn't so much of a need to get away, rest, and relax. I think the farmer or rancher is the ultimate example because that isn't so much work, as it is
life. You wake up and live it; eat-piss-poop, and sleep, to have the energy to do it another day...
I think that's what's so addicting, for me at least, about hot rodding. It's a lifestyle, not a job. You live, eat, sleep, piss, $#!+, and breathe, it. I don't end my week thinking, glad that was over, I need some rest and relaxation - I really never stop, don't want to stop, until there's no air and blood flowing in and out of my body. It's not a money thing either (my wallet and bank account will confirm that), it's passion. I've noticed that when I stop to "relax", I am usually preoccupied with getting back to my "work" (physically, because mentally, I never stopped).
