Absolutely... temporarily being far more rigid-minded than I am would be fascinating. And knowing that the alarm was ticking and that I was going to return to being my ordinary way of being would likely be deliciously terrifying, like a serious version of a roller coaster.

But, sure, if we posit that the technology is limited such that temporary changes of this sort aren't possible, then I wouldn't do that if I were the only one of me... though if there were a million of me around, I might.
