MORE... HOW COMES????

Lil'Sis

Was off once again the other day after I told her about putting her questions on my blog.
She said "Here, here's another two for this Baba Doodlius friend of yours to try and solve, they have been driving me mad for years!"

How Come?.....

1. When the sunlight is so bright it hurts your eyes, how come it doesn't hurt anymore if you shut just one eye?????
(Bet you are all outside looking up now trying this one out!)

2. Man nipples? How come men have nipples? Lil'Sis, not having researched too extensively into this says she thinks only humans and primates have man nipples, but why? Why hasn't evolution eliminated them by now as they are of no use whatsoever!

Over to you, Baba Doodlius!
