Our colleague, Greg Gwash, who now resides in Santa Fe New Mexico, sent this excellent article from “Yale Insights” to me today with the following comments: “Worthwhile article on the risk of repeated activities, like the Gym, or the Bus, or going to work!” I had not considered repeated activities and the risk before reading this article. Many thanks Greg.
