Would you rather go back to age 5 with everything you know now or know now everything your future self will learn?

Everything I know now and get to be 5 again??
I bet I wont drink that grape juice with a dead giant ant in it a second time.
I wont tickle Katie while she hangs upside down on the bars.
I wont be nearly as shy and timid.
Gawd yes.
5 it is!
