Some just starting out now should try for a trade such as pipefitters or welding. Direct from high school, they don't even want college types. Of course, for those trades one has to learn to do actual trig calculations, but they use calculators now. Get to journeyman level and you can write your own ticket just like you had a Doctorate.
The pay may look appealing, but I have many friends who are retired welders who live in perpetual pain from flash burned retinas. The job is like a professional athlete. Good pay while you can do it, followed by a miserable disability retirement.
