4. Insects such as termites and ants provide 10% of the protein consumed worldwide. Where insects are an integral part of a diet, they contribute as much as 40% of protein.       In the United States, it is estimated that every adult unconsciously consumes one pound of insects each year due to garden produce, poor restaurant and home hygiene, and commercial foods for which the USDA allows a certain amount of insect fragments. Peanut butter, for example, is allowed to have 30 insect fragments per 100 grams.

5. Women are more susceptible to the effects of alcohol especially  wine than men partly because they have less of an enzyme in the lining of the stomach that is needed to metabolize alcohol efficiently.

2. 100 years ago: Most women washed their hair only once a month using egg yolks for shampoo. Eggs cost about 10 cents per dozen.

3. The reason why we nod our heads for “yes” and shake it for “no” was first explained by Charles Darwin. He related the gestures to a baby’s nursing habits. The nod, the forward head motion, is the breast-seeking pattern. Shaking the head from side to side – gesturing “no” – is a breast-rejecting motion. This is confirmed by the fact that a baby born deaf and blind will nod for yes and shake its head for no.

4. It is believed that Shakespeare was 46 around the time that the King James Version of the Bible was written. In Psalms 46, the 46th word from the first word is shake and the 46th word from the last word is spear.
