For what?

A friend has sent this message about a consideration made by the Brazilian nobel prize winner Dr. Drauzio Varella:

"En el mundo actual, se está invirtiendo cinco veces mÃis en medicamentos para la virilidad masculina y silicona para mujeres, que en la cura del Alzheimer.
De aquí a algunos anos, tendremos viejas de tetas grandes y viejos con pene duro, pero ninguno de ellos se acordará para que sirven".

It means:

"In today's world, they spend five times more for virility medicines for men and silicone for women, than for curing Alzheimer. In a few years, there will be women with big tits and men with hard dicks, but they won't remember, these are for doing what!"
