Just a bit of nitpicking - Aviv Or is definitely a she. I saw her last week :)

In Hebrew - Etz or Pali which translates to Tree or Pali (Pali is not a word in Hebrew). These two terms come for the time of the British mandate over Palestine. The English "heads" was transformed to Etz, even though there's currently no head or tree on that side of the coin. Pali comes from Palestine, the writing on the other side of the coins back then.
