ticklishness decreasing then increasing

[SteveTheTrout]

Hi all -

I've read posts in which people say that ticklishness has increased with age (probably less common) or that their ticklishness has decreased with age (probably more common). Has anyone heard of, or experienced a change in ticklishness and then a reversal back to the original state? Say, you were ticklish when young, became less ticklish as you aged until surprisingly your ticklishness increased again...or vice versa...
