What is that thing which girls do once in lifetime and that same thing boys do every day?

Half of you is exactly as old as your mother. That is because the egg from your mother that was fertilized by your dad's sperm, was present in her ovaries the day she was born.

New sperm, on the other hand, is produced constantly in the male testicles. This process takes around 130 days for sperm to be fully formed, ready to die or create a new life.

So, men manufacture new reproductive chromosome-containing sperm every day, whereas women only manufacture their entire lifelong supply of chromosome-containing eggs once in their existence. This, in fact, already happens before they are born.

Quite enchanting if you think about it, actually.

Maqabir (Graveyards).

Explanation:

The riddle shown above is the imprecise translation of an Arabic riddle. The riddle in its correct translation is "Men use it thrice a day, while women only use it once in a lifetime." The answer to this is Maqabir or Graveyards and it is related to a Muslim tradition where men enter the cemetery "three times a day" as they bury the dead three times between the forbidden temples, while women only enter the graveyard on the day of their burial.
