Do you want to live a long life? You probably do, and here's some advice: stay in school!

A new study from Harvard University found a stunning correlation between the lifespan of people with at least one year of college, compared to those with a high school education or less.

People with at least one year of college lived longer by nearly a year and a half from 1980 to 1990

But those with a high school diploma or less gained only about six months and the gap is growing.

These days almost everyone owns a cell phone, but not everyone knows how to use it.

Here are few do's and dont's on cell phone etiquette.

First, your ringtone may be pretty cool, but not to everyone, so if you're in a public place or on a date try putting your cell phone on silent.

Texting during a movie can be just as rude as making a call. You'd be surprised how bright your phone can be in a movie theater.

So if you really need to text someone, step into the hallway.

Also, most people shorten their words when they text, but be sure you and your friend are on the same page before you do.

For instance some people use "LOL" as laughing out loud, but others use it as "lots of love" so you may be sending the wrong impression...

Ooops!

What urks you most about people using their cell phones? Do you think most people know how and when to use their phones?

Do you remember a time when you were annoyed by someone using their cell phone?

Let me know!
