I'm decidedly out of the trades as an adult.
Mostly, this is because of my folk's parenting in general. I was not good, due to the stresses of said work and business. But I imagine that's true of most small business owners.
But, it's also because the trades are quite hard on the body. I'm fully not kidding here when I say that my jeans were so dirty that they stood up on their own. Again, kid's jeans, and it wasn't every day, but at least twice a week. Heavy machinery like lathes will literally tear your arms off and beat you to death with them. I've grabbed 220V before and my Dad had to break the circuit with a broom handle, leaving quite the bruise on my arms, not to mention the near death of that kind of shock. Don't get me started on car exhaust and brake cleaners.
Auto repair may not be very exemplary of the trades as a whole, but I choose to take showers after work now.
