How can learning braille be beneficial to a sighted person?
Ooh! I’m a sighted person, and I know Braille! Story is, I got interested and brought a friend along with me. We both learnt it (off this sheet), and both now know most of it. We sometimes communicate in class with Braille messages (we write it in pen and it isn’t really “true” braille through touch). But yeah, Braille is fun with friends. But as you said, Braille might help IF you go blind. Also, knowing Braille, you could probably work with and teach young children with impaired vision. And apparently, sensitivity of your fingers increase if you practise Braille (with touch, that is). So this might benefit you somehow…
