Ants
Ants are very resilient.
Before my divorce we had a house in a village on Parnasus, a mountain four
hours out of Athens so we did not go often. At the time there was no electricity
and no running water, we had to go downlhill and fetch water from the shady
springs. The water for the small sink was added to a small hanging tin tank,
and was the first thing checked when returning. After a long absence, I checked
and saw a black mass floating on the remaining water. I wondered how leaves had
gotten in there and then to my surprise I saw that it was a ball of ants, God
knows since when, floating on the water. The top ones were moving. I took the
container and emptied it on the cement steps outside, to see how many had
survived. All the ball walked away. Obviously it was continuously rotating by
their movements , and they all survived.
