The real threat to whales is whaling, which has endangered many whale species.

No matter what happens, somebody will find a way to take it too seriously.

A person who is nice to you, but rude to the waiter, is not a nice person.

You should definitely have a travel agent. Why go through all the hassle of dealing with airlines, hotels, and rental-car agencies yourself, only to see the arrangements get all screwed up, when with just a single phone call you can have a trained professional screw them up for you?

9 saw the first direct-dialed long-distance telephone call, between New York and San Francisco. Of course, back in that primitive era the parties had to speak to each other manually; today one or both ends of the conversation would be carried on by a machine.

Here's a simple experiment that you might want to try if there is absolutely nothing else going on in your life. All you need is a cork, a bar magnet, and a pail of water. Simply attach your magnet to your cork, then drop it into the water, and voilà (literally, "you have a compass")-you have a compass. How does it work? Simple. Notice that, no matter which way you turn the bucket, the cork always floats on top of the water (unless the magnet is too heavy). Using this scientific principle, early hardy mariners were able to tell at a glance whether they were sinking!

When the boomers started to have kids reach adolescence, there was suddenly this feeling that they needed to protect their kids from all the same things they did when they were kids. Which I guess is a natural tendency, but it makes for a less fun society.
