But we are all getting worse.
I basically don't drink but I believe that my body control has gotten worse. Back when I was in school one or few times I slipped on ice and had a fall. I was able to stop myself with my hands and not get injured. But this year I had a fall while chasing a bus. I was not able to react in time and hit my leg quite bad. it took about a month(?) until it healed completely. I guess that means that not only am I losing a bit of reaction time but also I am getting more fragile because in the past I was never injured for so long. Getting old(er) sucks...
This is what happens with age, but also happens happens faster with inactivity. One of the biggest issues people have in old age is their balance, and that comes down to foot strength and mobility. In the past we used to walk barefoot everywhere on many different uneven surfaces, now everything is in shoes and on smooth ground, so our feet have lost their ability to keep us upright and moving well.
