Sorry about your eyesight. It's funny, I've been thinking a bit about how my puppy perceives the world through their noses and wondering how different the world must seem to them. In any given moment they experience the way the spot where they are standing IS and how it WAS in the recent past and know that there are things inside other things that we have no idea are there. What must that be like? And I know that like that, there are people with amazing hearing that can listed to a symphony and hear all these nuances that don't exist for me. Similarly a guy I worked with once told me he refused to use a wireless mouse because it was too slow. He could only use wired ones because he had sort of superhuman eyesight and the slight delay was unbearable for him. I laughed but turns out he had been a professional video game player, one of the top in the world and his hand/eye was off the charts compared to normal folk. In some ways we're all a little bit hobbled with our own senses. But we do the best we can with what we have and use tech and science to try to fill in the gaps whenever we can.
