The elixir of life (№ 268583)

Alexander the great spent his entire life searching for the elixir of life that gives immortality, and I found him in the Arabian desert. The elixir was found in a cave. What a joy! Alexander danced for joy. He went there alone, not taking even his closest friends. Entering the cave, he saw a spring coming from under a huge crystal that glowed all the colors of the rainbow. Spellbound, he looked at this miracle and was about to drink, suddenly heard cawing. Alexander flinched. Looking around, he saw a very old man with a beard to the ground. Next to him sat a Raven.
The old man said:
- Before you drink, think carefully. I drank this water and live for several centuries. If you knew how tired I am! I'm desperate. I want to die and can't. I'm fed up with life I have no desires. Life should be updated, and it can be updated only through death.
They say that Alexander was so affected by these words that he ran out of the cave, jumped on his horse and, without looking back, rode until the sun went down.
