I loved "where in the world is Carmen Sandiego!!!" when I was a kid!!!!
Bahahaha to the dogs barking comment, I've so wondered that!!
I have often wondered why we have evolved with our nostrils pointing toward our mouth.
Knowing that the nostrils can expel contaminants (and boogers!) by 'sneezing', why would they point straight to a second entry point??
Very interesting thread so I'm subbing
Little fact regarding birds, they roost mainly. The foot of a bird wraps around the branch eg, some toes forward and some back so they don't fall off, this is actually their muscles in a relaxed position, they have to tense their muscles to release the branch as such.. This stops them from toppling out of the tree once asleep!
Hope that made sense!
If you snipped the short hair on your arm, (not actually removing the whole hair, just cutting at the halfway point) how/why does it grow back to it's original length?But if you left it alone and did not ever cut it it would just remain the same length? How does the hair know that it has been cut and proceed to grow and then stop at a certain length??? The hair on your head continues to grow all the time, from the root, but the hair on your arm stops at a certain length... until you cut the tip off, it grows again???
How birds sleep...but in trees obviously
