living without a sense

i've sometimes wondered what it would be like to be deaf or blind, or maybe even both. i couldnt imagine having to go through life without one of my sense, but people around me are doing it every single day. i learned today that if you are born without or lose one of your senses, the other 4 you have will become very strong, and will take over the place of the one you are missing. if you were deaf, you wouldnt be able to judge peoples moods based on the volume of their voice, but your sight would let you understand and interpret their facial expressions. if you were blind, you would be able to do the opposite. but imagine if you couldnt smell anything, how would you know if something was burning, or what exactly it was that you were eating? or what if your taste buds werent functional, how would you view food and decide what you wanted to eat? or would you have to live by a strict diet? or what if you couldnt even feel things through touch? what if you laid your hand on a hot stove, but you didnt know your skin was being burned? how do they adapt with handicaps like this? are there ways that doctors and families can help, or can come up with some sort of plan for how these individuals could be able to live as independently as possible?
