I did the same things, in construction and quarry work. Worked out 8-12 hours per day, 5 days a week, was outside almost the entire day, and was in fantastic shape. I never felt better than when I did that, and it was the healthiest I've ever been in my life. Getting paid while getting a work out and being outside, most people don't understand what a blessing that is, because they only see it as "hard work". Unfortunately, the mass importations of Juans, Miguels, and Joses have massively depressed the wages for manual labor jobs.
