You Can Have Any Super Power, But if Someone Finds Out… You Die

Everyone has asked this question before, but I’d thought I’d put a little spin on it. You can have any super power you want, but if someone is able to notice your super power you’re dead. So if you choose the ability to fly and someone see you flying then you die.

You can either take a big power that would increase your quality of life, but then kill you shortly after you got it, or you could pick a much more subdued power that no one would be able to notice and live a lot longer.

What would you pick?
