In 1965, the CAS Chemical Registry System listed 211,934 synthetic chemicals. In 2006, that number rose to 88,758,285 and it’s still growing. Many of the chemicals are in products you use everyday from cosmetics to plastic toys.
Many soak through our skin or are breathed in and can be detected inside our bodies. For instance, researchers sprayed the common household oil, WD-40, on volunteers’ fingertips, and detected it in their blood five minutes later.
The average American male has a sperm count 75% lower than 40 years ago. Could this be partially due to these chemicals?
We remember one trillion things in our lifetime.
Computer scientists say our brains have a storage capacity approximately the same as an 11-terabyte hard drive, which with current solid-state technology can be stored in an area about the size of a fingertip.
Our eyes are each equivalent to a 137-megapixel camera, roughly ten times higher resolution than a typical modern digital camera.
These comparisons are a bit rough, because humans are made from wetware, not hardware. For instance, the retina has much greater sensitivity near the center than at the edges, while a camera has uniform sensitivity. The memory of a hard drive is digital. Each ‘cell’ in a hard drive can hold a one or a zero. Each cell in the human brain is more of an analog mechanism, firing or not based on many input factors.
What is a dinosaur worth? You can buy a large skeleton from a professional dinosaur hunter for about $300,000.
I have heard that planting marigolds in your garden will keep deer away. I tried it. The deer ate my marigolds.
Bananas do not grow on trees, they grow on big herb plants.
The reason humans walk upright might be because we learned not to drag our bodies in cold, wet snow.
The world’s largest seeds weigh as much as 40 pounds each and although they look like coconuts, they are up to three times larger. They are from a rare type of palm tree.
The world’s largest flower is also one of the worst smelling flowers. Rafflesia Arnoldii is often over 3 feet wide and its petals are almost an inch thick. You wouldn’t want it in your garden, however, because it smells like a rotting animal. The flower is attempting to attract flies for pollination.

The fine machine lubricating oil for which the sperm whales were hunted was mostly in their heads – up to 500 gallons (1,800 liters) of it in one whale. Until modern chemical technology, nothing lubricated as well as whale oil. Now there is even more valuable stuff that forms in their intestines – ambergris. This foul-smelling grayish-black stuff is used by the perfume industry, not for its smell, but because it has been found to cause other smells to last longer.
Within the next few years, doctors will start using ocean coral to replace bone in surgery. It is chemically similar to human bone and implants are well accepted by the body.
