Only 7% of Americans say that they don't use the Internet. But according to Pew Research, it varies from just 1% of those ages 18 to 29 years old to fully 25% of people 65 or older.

For those older folks, that's a shame. A study just found that using the Internet regularly cuts your risk of dementia in half, and the most benefit comes from using it around two hours a day.

Researchers from NYU followed 18,154 dementia-free adults, ages 50 to just under 65, for up to 17 years. They found that regardless of a person's level of education, race-ethnicity, sex, or generation, Internet usage cut their dementia risk by 50%.

Why would getting online make a difference?

Learning, playing games, connecting with friends, and having a posse and a purpose all contribute to making you feel younger and protect you from cognition loss. 

If you don't have a computer at home, visit your local library to get online — and while you're there, check online for www.GetInternet.gov, the Affordable Connectivity Program (ACP), and Lifeline. They are federal government programs that help eligible households pay for internet services and internet connected devices.

However you do it, the rewards of being and staying connected to the larger world and all that technology offers can improve your quality of life today — and for many tomorrows.
