Service for what? I'm in my 40s and now that I think about it, I've never had to call a plumber in my entire life. The only time I can think of is my parents calling one when they got a new dishwasher 25 years ago.
That's not new though. My colleague does IT for a few years then works as a construction worker for a few years, depending on the market. He's ready for anything :-)
