When did "play" change?

I have a bit of a pipe dream.  I want to be a toy maker.  professionally.

Why?
Well, I like things that are fun.  
I'm also pretty critical of the toys available in Toys R' Us (who decided to throw-up pink all over the girls' aisle?)

This being said -- I've got "toy making" on my to-do list (along with a million other things like correctly pronouncing items on a French menu, so everyone can say "wow, look at that sophisticated lady" or being able to name more than 5 African countries without going to Wikipedia).

We'll see when that happens.  In the meantime, I've been fascinated by articles on toys & play, like this one my college friend, Allison, shared with me, which I'll discuss now.

All it takes is 1%

Here's a riddle for you.

A father and a son get in a car accident.  The father dies, but the son is sent to the hospital with serious injuries, needing emergency surgery.

The doctor comes in and says, "I can't operate.  It's my son."

How is this possible?
