I wish I had the superpower to turn on/off any of my senses at will, where off equals still allowing it but so little that its as good as being off.
Choosing that I don't want to see, choosing that I don't want to hear, choosing that I don't want to feel, etc. Turning the senses off will obviously not protect me against the source, but can make an otherwise unbearable situation bearable. In a room that is super bright, I could turn off vision. Not being able to see, but not required to close my eyes and still be affected by the brightness. Neighbours that are loud during the night, I turn off sound and sleep peacefully. Having an injury on my arm, turn off pain for the moment.
@Polana, That is actually a massive superpower. Being able to leave a message to past you is similar to being able to predict the future. Knowing what will happen and adjusting it is so fundamentally altering that you could predict the lottery numbers and get a huge sum of money. You see what the lottery tickets for today were, then leave a note to past-self with those numbers and voila, you win big sum of money.
So in fairness of the spirit of this topic, I'm deleting your post. Feel free to repost an altered version that adds a huge constraint to stop it from predicting the future, etc...
