Smell, I already have a shit sense of smell anyways.
Literally has no influence in ones life.
Without taste you could eat something expired and not notice, not to mention that food is love food is life.
Who would want to be deaf?
Or Blind?
Not having any feeling anywhere would be a nightmare.
smell definitely. vision and hearing are way too important. i like messing around with stuff with my hands and like fixing stuff so tact is important for me too. taste also important because i like eating
