&#62; No sense pushing things when the world is nuts.<p>Yet we have no qualms about our kids playing sports where they easily can break their necks and knees. If you go to any school in US, you'll see students with casts and bandaged knees and elbows. Most of those are sports injuries. See how many children have "science" related injuries -- you'll probably see none. So it is not that we want to protect our children, because then we'd have to cancel football, but instead we end up teaching and perpetuating certain attitudes and values that ultimately will put our country at a disadvantage.
