I found out locally that Mayo Clinic pays people to become phlebotomists and lab technicians. They pay for all the schooling with a commitment to work for them for X years. I would higly recommend your friend pick out some things she enjoys, and speak to people in the industry on options... even if it isn't in a lab as suggested, there are probably other opportunities out there if you look.
I was listening to a writer about following your passion, and something she said struck a chord with me:
Sadly enough... people are now working into their 80s quite often, so it is never too late to change your mind, and do something you like. Do it...TODAY! Even going to medical school or law school makes sense when you are in your 40s because you aren't even half way through your average work life...
So, with that being said she may have another 30+ years of working...she better do something she likes. I would focus more on what will make her happy vs. just a job to fill in the cracks. If she follows her passion she will find something!
