They tell us boomers that we have to "use it or lose it." (Stop sniggering. I know what you're thinking, but that's not what I mean.) Joints stiffen up if we don't make a concentrated effort to get them moving, vitamins are not optional, and spending too much time on the couch quickly results in a body molded to that piece of furniture and not good for much else.
It's daunting. I'm at the age where I'd like to stop running about, but now it's mandatory! I worked out with a trainer at my fitness center yesterday. By the time she made allowances for my stiff parts and my previously injured parts, I was pretty much doing a sitting and standing routine I would have laughed at 20 years ago. And it was hard to do! I'm getting humility the hard way.
Much use of aspirin made it possible for me to sleep last night. I'm going back today. I think the warm therapy pool will be my first stop.
