You are not a point particle. At least I assume.

Your arms etc. would have to accelerate at a different rate than say your liver to achieve the same RPM as they would end up moving faster.

Therefore your arms and liver experience different relativistic time frames - your liver be getting older faster dude.

Boy isn't that the truth, I regret every cocktail. No I don't.

If only the world were to rotate, then no part of you would undergo any acceleration.

I'm probably wrong. I am drunk.
