Would it be possible for you to start the podcasts with a single sentence noting the sponsors and then do the detailed information about them at the end ? Your podcast has provided the most useful information to me, especially the one about sleep. I've recommended the podcast to several people including my wife son and daughter. My wife and son stopped listening immediately when they heard the long beginning about sponsors. My daughter persevered but still complained to me.
I believe you have briefly mentioned "classical" memory training/techniques, such as mnemonics, linking words to pictures and associations in several episodes. My impression is, and I might be completely wrong, you see them mostly as a crutch. However I feel like they might be a useful tool in one's arsenal if you want to remember a lot of information. I would love to hear an in-depth and science-backed discussion about the pros and cons of such techniques.
