No, not because of the YOLO, but because I think that, with being immortal, I would be forced to watch those I care about age and die around me, while I live on. It would be a lonely existence, every time I'd make a friend, they too, would eventually be gone, and I don't think I could handle that.
Would you push the button, if you could become invisible to those around you, but you would have to think about sad things every time you wanted to activate it?
