1. SOPHOMORE = SOPHOS + MOROS = “wise” + “foolish” (Greek)
  2. I just learned that (1) Thomas Crapper did not invent the toilet, and (2) the word “crap” does not come from his name. Now I feel totally disillusioned about my knowledge base. Bummer!
  3. My car takes 91 octane. Gas is sold locally in octanes 87, 89 and 92 or 93 octane. So I must average octanes. One would think that gas stations would have figured this arbitrage out. But it is always strictly more profitable for me to mix 92 and 87 octane than 92 and 89 octane. So drivers: avoid 89 octane!
  4. I am such a sucker for Venn diagrams. This one categorizing all drugs is for the ages.
    Disclaimer: For me, caffeine is a stimulant and alcohol is a depressant (my nightly glass of red wine, angel face). I have had nitrous oxide (hallucinogen & depressant) two or three times. I have fended off the peer pressure to consume all others – does that make me a geek or a nerd? Curiously, cannabis – or marijuana (Mary Jane) – is  simultaneously a stimulant, hallucinogen, depressant, & anti-psychotic.
