Serious If you had to pick 1 superpower, what would it be?

Initially I would have said immortality but that could have some major downsides towards the end of the Universe, not to mention out living everyone you care for. So maybe just decelerated aging, most of the perks of living forever but still being gone before the Universe does whatever it will one day do.

Although the thought of being a 90 year old for centuries doesn't sound fun, but by then we will probably have cured most age related issues any way.
