Head and Brain

#4.The human head is made up of about 456 trillion atoms….. quite a few…





#5.When making a judgement on if an action would have an affect on others, teens were much less likely to use their medial prefrontal cortex than adults, the area of the brain associated with empathy and guilt.

#6.On average, over time, human brains have gotten smaller. However, brain size has nothing to do with intelligence.

#13.A fingernail grows 1/8 inch per month and can reach 4 inch growth in a year.





#14.Your hair and nails do not actually continue to grow after you have died, it only appears that they do due to the shrinking of the skin around them.

#15.Due to a seasonal variation in androgen (a male hormone) production levels, beards grow quicker inspring.

#16.Poor circulations within the legs (possibly due to narrowing of the arteries) can eventually lead to a loss of leg hair.

#17.Lost hair clogs up the pipes so quickly because they are resistant to cold, change of climate, water, acid and corrosive chemicals.

#18.A study on 117 male members of the Mensa society (a group in which you need an IQ of over 140 to join) shows that the higher IQ tended to have thicker body hair, and also hair on their back as well as their chests.

Emotions and Your Body


 

#19.Squinty eyes and a pinched up nose are the universal facial signals for disgust. This is opposed to the fear response which widens the eyes and flares the nostrils.
