Science has FINALLY figured out why our hands, toes, and other areas of our carcass shrivel up like prunes when we spend too long in the bathtub or pool.  I never realized there WAS NOT a good scientific explanation...but there wasn't!  The theory was always that the shrivilling(pruning) came from water absorption.  Which is not correct and boring!  So a team of scientists at Newcastle University in England studied the shrivelling, and came up with the REAL reason it happens.  They proved that when our fingers are pruned, they're actually MUCH better at GRABBING things that are wet...kind of like a tread on a tire!  Ancient humans actually evolved that way because they needed to grab wet food after it rained, or food that was growing in the stream.  And our toes shrivel up for a similar reason...so we can walk better when it's wet.  And that's where the information ceased!!!  I guess...the treading...gripping....yeah....WHATEVER!!!
