I'm always thinking about going back to school to learn some new trade. I'd really like to learn to weld but probably not for a career at this point. It's never too late and at 62, you could work for several years more.
One of the automotive machinists I use is in his very late '70s and I just dropped-off a diesel cylinder head w him the other day. He graduated from Hollywood HS in 1960 and then had his own shop in Hollywood for decades. Talk about living through the golden age of hotrods and muscle cars...he's had a blast.
Although we are talking about learning trades, my sister is back in school @ age 55 getting her Masters in Public Health in an accelerated University program. She is an MD who recently dissolved her partnership in a very successful medical group and could retire but wants to keep working, though she was burnt-out on the job she had. A complete career change @55! She is my inspiration.
