1. Don't stick out your tongue if you want to hide
your identity. Similar to fingerprints, everyone
also has a unique tongue print!
2. Your pet isn't the only one in the house with a
shedding problem. Humans shed about 600,000
particles of skin every hour. That works out to
about 1.5 pounds each year, so the average person
will lose around 105 pounds of skin by age 70.
