At my age I’ve noticed that on a lot of people.
Gravity has been increasing for at least 40 years now. I have noticed that:
I can’t jump as high as I could then;
I can’t pick up things I could then;
When I fall down, I hit harder and it hurts more;
When I get on the scale, it reads considerably higher than it did back then. (This last item is scientific, measurable proof.)
