Comment Teach and let him find his own. (Score 1) 614
I'll throw in for Jamie and Adam, since they are both really well known and worthy of the adulation.
Far better to have your children live the life of math and science, makers and doers, and let him come on his own. Expose him to your (our) world and let him decide for himself.
Finally, remember that there is no reason he couldn't also like Hockey, or football, or anything else that the muggle world indulges in. We do our children (all of them) a huge disservice when we act like to be a geek you can't also play a sport, or be interested in something outside of the traditional geek pursuits. Geekdom is creeping ever farther afield to encompass more and more (geek cooking, geek fashion, etc.) Heroes need to be something one chooses organically, so take him on a journey, don't hand him one.
