As a mom who nurses her baby I found some fun facts when looking for info about nursing:
The natural nursing period for mans is 3-7 years. 6 momths fulltime, then in addition of solids. It can be observed in many non-western cultures. It also makes sense, as the immune system of a child isn't finished until it's three years old, and until that time it can still benefit from moms immune system.
Babies actually habe instinctual behavior to find the nipple and latch themselves. Moms who have nursed may recognise the tossing of the head, pushing with the arms, throwing the head back and kicking with the feet. If you lay a young baby with his belly on your belly, these movements help him reach his destination. Pushing the arms to reach the right height, moving the head to find the exact location, kicking the feet to crawl a bit up. I tried it myself with me then-3weeks old, and he found his mark in two minutes, with a perfect latch.
On other topics: there is a frog that lives in an area where it freezes during the winter. He lets himself freeze solid. In the spring he aws and is his old froggy self. This is possible because the fluids in his body are adjusted for that (sugary) which prevents cell damage due to frost.
For the people who may remember the soundtrack from inception: in inception, one of the plot points is the use of the melody 'je ne regrette rien'. Another plotpoint is how time slows down in each dream layer. In the soundtrack, when things get really tight, there is this heavy bassy sound that goes like 'duuun dum, duuun dum'. This is actually the start of the song I just mentioned, but just super slowed down. Here is a youtube link which shows what I am talking about: http://www.youtube.com/watch?v=Q2sD3QvwnjY
Next topic: people often view witch burnings as something of the middle ages. However, it didn't happen so much back then. It didn't really start as we know it until the 15th-17th century. Before that time the officials of the church mostly shrugged about such issues and went like 'oh, silly superstitions'.
Next topic: dogs are not color blind. They can see two primary colors. Humans can see three primary colors. There are animals that can see over ten primary colors. Compared to them, we are very color blind.
Next topic: scientists have wondered where the wide variety of fur colors in dogs came from, and the fact that they bark. Wolves don't have such colors and don't bark. An experiment with snow foxes showed how these attributes came to be: a scientist bred snowfpxes for one trait: friend.y behavior towards humans. Some foxes are shy and run away quick, some dared come closer. The latter were used for breeding, creating friendlier and friendlier foxes. However, these foxes also gained the following traits, which they hadnt been selected for: spotted fur, floppy ears, and barking. It is indeed known that the change in one trait can bring about the sudden appearance of other trait changes.
