Most mammals normally cease to produce lactase, (and become lactose intolerant), after weaning. However, some human populations have developed lactase persistence (and therefore can eat dairy after adulthood). This said, research reveals intolerance to be more common globally than lactase persistence. The frequency of lactose intolerance ranges from 5% in Northern European to more than 90% in some African and Asian countries. That would mean that 95% of people form European stock and 10% of people from African and Asian stock are "not lactose intolerant".
About 2.5 to perhaps as many as 3% of the US population suffers from alcoholism.

I don't know but it is completely normal if you suffer from hemophobia (fear of blood). I have it too It might help to know that 10% of the population suffers from trypanophobia, the fear of injection.

thirty seven percent of the population suffers from a fear of crowds
Europe's population growth rate is about .2% which means it loses about 1,600,000 per year. The west still has population growth but it is the east who suffers from population declination.
