Having bad eyesight
The tree 20 feet in front of me is a green blob. I constantly wave at people thinking they're people I know. I can't go anywhere without a piece of plastic/metal on my face. And WHAT DO YOU MEAN I HAVE TO PAY TO SEE!!? Why are humans designed to have eyesight that gets worse as we ageโฝ
Aside: obviously, opticians and the people making the eyeglasses should be paid for their work.
