Facts my dad emailed me:

Did Nero need glasses?
Historians have reason to believe that Emperor Nero was nearsighted. He reportedly watched performances while holding a jewel with curved facets in front of one eye.

What are varicose veins?
Varicose veins are stretched, dilated veins whose valves do not work properly. The Arizona Heart Institute & Foundation reports that women are three times more likely to develop them than men, and people whose jobs require them to stand for long amounts of time often develop them.

How many eyes does a spider have?
Most spiders have eight eyes. These are arranged on top and near the front of the head, usually in two rows of four each.

Is the world round or not?
The world is not round. It is an oblate spheroid, flattened at the poles, and bulging at the equator.

Why did Bissell invent the carpet sweeper?
M. R. Bissell had a china shop in Grand Rapids, Michigan, and was allergic to the dusty straw scattered on the floor after unpacking china from crates. So, he invented the first carpet sweeper in 1876 to clean up the mess and protect his sinuses.
