Today we woke to a very chilly house with the furnace running non-stop. A quick look at the digital thermometer I got for Christmas said that indoors the best we could do was 51 degrees F.

…maybe that’s because on the other side of the window, outside, it was -18 degrees F! Yikes!

On top of that, I look outside and the snow is blowing horizontally. The wind must be 10-15 mph. Brrrrrr!

Is this the first time you’ve discovered this global website we’ve created?

If so, welcome! After less than a year, we are getting 40,000+ views a month from people living in 150+ countries. So why are two dentists from Vermont running a project like this for the wider world?

To tell you the truth, we started Ever Widening Circles because we had reached a tipping point: we just could not take the negativity of the 24-hour news cycle one more minute. We knew the world was an amazing place, but we could not find an ad-free place on the internet to restore our hope and satisfy the curiosity we have about everything.
