Do you also have a saying in English that goes something like?:

-En esta vida, un hombre tiene que: tener un hijo, plantar un árbol y escribir un libro.
(In this life, a man has to: have a child, plant a tree and write a book.)

So, there you have it!

Seriously now, I think that's such a personal choice, because it must be so hard! It should be MMan himself if he has the urge to do it who decides.
