If you had to disable one ability that you possess but it could not be one of your senses in its entirety nor something so insignificant that it didn't affect your regular life what would you choose?

By “it could not be one of your senses in its entirety” I mean you cannot answer with ‘sight’, ‘hearing’, ‘touch’ etc but can answer with “the ability to see people” or “the ability to feel skin” etc.
I admit the question is somewhat confusing as it asks that a person disregard something of ‘medium value’ so to speak but I feel most will atleast understand the situation I am attempting to describe.
If anyone would care to offer an answer please explain why. I am curious of what peoples explanations for their choices shall be.
