You'll be surprised at the strongest predictor of how long you will live

I will be 70 years old later this year and would love to make it to 100. I thought that mainly meant some good genes, eating well, exercising and a huge dose of luck.

Yes of course, those things matter. But I was amazed to see the top two predictors of a long life in this TED talk by psychologist Susan Pinker:

1. frequent face-to-face interactions
2. close personal relationships

So I may be in with a chance!

It's also another good reason for us all to talk more face-to-face, build strong relationships and community.

You can find the full talk here on TED.
