That sounds good, never take anything for granted, my grandpa slowly went blind, he told me he was driving home from work, came over a hill and the sun was extra bright that day.
He had not had his eyesight grime that day on.
I remember him and I used to ride the city bus into town when I was a little kid, he would tell everyone I was his eyes, he got around pretty good, as long as I was holding his hand.
