True,
But you see, you can prevent kaalapan with sunblock etc.
On the same note there is nothing to prevent mental malnourishment that causes these same children to grow up as stupid idiots.
Its a better investment on kids, as when you pass away they are not like zoo animals let loose in the wild.
Tl dr.
You can rejuvenate skin, but there is no cream, tablet, therapy or voodoo smoke to fix stupid, so its better to prevent stupid.
