That is a very good though. I sure would hate to put 100% into my 50% and the other 50% of the company only allow 10% because the other 90% is in 9 other companies... You said it better.

I like how the graphs that show the correlation of lead and crime is on two largely different time frames. Yes they have similar patterns but you can match anything up if you mess with the x and y axis enough. The dates should match...

I believe they are trying to show how there is a delay between ingesting all the lead and it having a noticeable effect.

I.e. it will take years for the the lead to have an effect. It's not instantaneous.

Why should the dates match, if you want to talk about a delayed effect?

The video format isn't supported. There is nothing on how to fix this. If I need a plugin to watch the instructional video to use the site I would make that plugin very easy to access. Just a though. Maybe it's just me though.
