I've been listening to these podcasts for years, usually while I am hiking. Each one is informative and fascinating. What a wonderful way to inform the non-scientist about the phenomenal discoveries all around us. I love each of your host's unassuming manner, wit, and intellect. Usually when I return from my daily hike, I have been so absorbed, that I don't even realize I was exercising. Lots of times I wish I could recall everything discussed, but that is not possible. However, when a related conversation comes up with family or friends, I find that it all comes back to me. Thanks so much for helping me to be more informed. This is far and away my favorite podcast.
