44. Scorpions dance to mate (and at least for David Attenborough, it works well to classical Spanish guitar)!

45. Pablo Neruda was the Chilean consul in Rangoon, Java and Barcelona from 1927-1945. This completely makes my day!

46. Jordanian taxis must have a working meter, so you don't have to guess what the fare is or haggle. It's very civilized, although almost always smoky and without seat belts.

47. Neruda wrote a poem about fleas:

Fleas interest me so much

Fleas interest me so much

that I let them bite me for hours.

They are perfect, ancient, Sanskrit,

machines that admit of no appeal.

They do not bite to eat,

they bite only to jump;

they are the dancers of the celestial sphere,

delicate acrobats

in the softest and most profound circus;

let them gallop on my skin,

divulge their emotions,

amuse themselves with my blood,

but someone should introduce them to me.

I want to know them closely,

I want to know what to rely on.

48. The flea is the second-best jumper in the animal world, behind the froghopper, but cannot swim.

49. Jane Wyatt, the actress who played the mother of Spock in the original TV series, was descended from Rufus King, one of the original signers of the US Constitution, and later an ambassador and senator.

"Spock, as originally described in Gene Roddenberry's 1964 pitch for Star Trek, is described as "probably half Martian, he has a slightly reddish complexion and semi-pointed ears"
