Sorry, but I have to laugh at you 50-somethings talking about aging.
I'm 74, still working 40 hrs per week, and thinking nothing of it.
I've had 4 heart attacks, hip replacement, right rotator cuff surgery, 4 back surgeries for discs wearing out and lower back fusion, two left forearm surgeries, and it goes on.
I'm on the FM9 waiting list and just hoping I'll live long enough to get one. I only signed up about 5 weeks ago.
My problem is that I'm digitally impaired, and will also need a laptop when I get the FM9.
Still, I do my homework ahead of time watching youtube videos, reading the manual, and am excited, albeit stupid, digitally. I read the manual and a lot of things are not making any sense to me, but the videos really help.
