Regardless every person being different from the next, spending days on end watching brainrot television is not a good way to spend your life.
Of course, I wasn’t suggesting otherwise.
Even with reduced mobility, a person can enjoy other things. Reading, writing, listen to music, solve puzzles, etc. There are numerous activities to persue.
My point is when you see Grandma sitting in the rocker on the porch she may be doing that not be because she’s there to enjoy herself, but because she’s incapable of doing other things, and even movement is problematic.
In essence we don’t get old, we just break down, and when we do, the lack of mobility and pain are your constant companions.
