I think you may enjoy this video. Jon Kabat-Zinn is a scientist and a mindfulness meditation researcher.
I've condensed a talk he gave at Dartmouth where he shows us just HOW important it is for our health to learn to come back to the present moment as often as we can.
Versus continually focusing on the past or future. Which our 'wandering mind' likes to do, unless trained.
AND he does so in a humorous way, which I always appreciate.
