These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic. Enjoy! Henson Shaving is offering 100 blades free with the purchase of a razor — just head to hensonshaving.com/MINDSCAPE and or use code MINDSCAPE at checkout.
