In my opinion, there are a few advantages to being blind and to being deaf. If someone is blind or deaf, all of their other senses will be heightened. They will be able to smell much better and taste more vividly than if they could see and hear. They would also be more confident in themselves because they would not have to worry about what they looked like because they would have no idea what that means. They would be able to have confidence in their abilities and not rely on their appearance to give them confidence. Also, although they would not be protected of all the negativity of the world, they would be sheltered from a large quantity of pain because of their inability to see the hurtful things of this world. Another more obvious advantages to being blind is all of the societal benefits. Blind people often have options that make life much easier for them. For example, they get better seating on public transportation.
There are also many advantages for being deaf as well. People who cannot hear can very often read lips very well which can be useful in certain situations. Deaf people have the advantage of not having to hear what they don't want to simply by turning off their hearing aid. Loud noises at night or bad music or annoying people are very easy to mute. Similarly to being blind, people who cannot hear often have more developped senses of taste and smell. I get headaches regularly from excess noise so I would think that deaf people would not suffer from that.
