I've got two of them, you've probably got two. Eyebrows, I was wondering why we all have these apparently useless appendages. So I googled it, lots of pages (I leave you to do your own research, it's interesting).
What other appendages do you wonder why we have them, surly only useful things survive evolution, or do they?
(Ok, I do think of some weird things)
don't have a problem with under 16's having free bus travel,BUT
