Just two short years ago I was fine, I'm thinking maybe the whole reader thing won't apply to me, then bam, in the space of a couple months I can't read small print. Now I've got like 10 readers; one in the bedroom, living room, office, in my cars, downstairs, in the garage, a couple at work, it's ridiculous. Yes, I could hang them around my neck, but I'm not there yet.
And yeah, I have knee pain and back pain, but the whole not being able to read words sucks worse.
