I am just curious about caffine. Where does it come from? A plant, a bean, chemicals or what? Is it man made, or just made by natural stuff? How is caffine made, and what is it made out of?

I was listening to the radio this morning and somehow it picked up a walkie talkie signal. And then I wondered, with all the radio waves, microwaves, and all the other types of waves, do they have any effect on the human body?

And today I found that the county I live in has the highest cancer rate of any other area in the U.S. My county is named ANNE ARUNDEL COUNTY, which is coincidently less than 20 miles from WASHINGTON D.C. Is that just a coincidence?

I never had anybody tell me this until my wife learned this today from someone at work. I couldn't believe it until I tried it. I had my wife go far out of range, and then I called her by cell phone. With the key in her hand, and me by my car door holding the cell phone, she pressed unlock on the key remote and unlocked my door. This is great if you lose your key or leave it in the car, and someone else in your family has an extra key to your car, and you can call them to unlock your door.

Man has a 5,000 year history of cannabis use. Smoking is a fairly recent development. It is safe, yet we are told it is dangerous and has no beneficial uses. That is not true. I want to find out how people use it and how it benefits them. Is it a medication? If so, how is it used? What legitimate commercial uses does it have? Serious answers, please.
