> Some folks just get there faster.

From my observation, most folks get there temporarily or faster in their own specific way.

I have friends who lost their hearing early for a variety of reasons.

There are lots of ways to have imperfect eyesight, or lose it temporarily. You can lose your glasses or not be able to wear contact lenses for a while.

Lots of folks with laser surgery eventually regress. Also the surgery itself has visual side-effects.
