1) We're taught that certain tastes in candy are the equivalent to a "natural" flavor. But it's simply not true. Next time you taste anything candy-style that claims to be Banana or Watermelon, actually stop and think about it. It bears no resemblance to either one of those real tastes, but if you taste it you immediately say, "Oh yes, that's banana / watermelon." Um... actually, it's not.
Unsure what to do with this philosophical conundrum.
2) Despite the fact that I live with two dogs (Australian Shepherd & German Shepherd) and two cats (one a Turkish Angora), it's MY hair that breaks the vacuum. Yes. A Dyson, nonetheless. One day my hair will rule the world, I swear it. Just ask the drain. Or the headrest in my car.
3) Once it's lower than 15 or so degrees you really can't tell the difference. You just walk outside and think, "Wow, it's really cold." The difference between 15 and -15 doesn't really register. Until you die more quickly. Then it probably matters quite a bit.
