Does sitting get less comfortable as muscle declines???

[PenelopeFlintstone]

This is a bit weird to even type, but as I was driving home last night it occurred to me that sitting in the car doesn't seem as comfortable and as natural as it used to. Sort of feels more 'squished'
Is it just me? Do I need to do squats? Has anyone else ever noticed that? I am 50, by the way, and far from a gym bunny.

Has someone altered your car seat position?

Are you wearing your winter coat for the first time in a while (mine has a slidy satin lining)?

Or yes could be part of age-related muscle loss.
Yup, squats will help that.
