When Carson was in Gr 2 his teacher had Carson leave the room, then she told all the kids to
stand up and put their hands in the air and she wouldn't let them put them down until they couldn't
do it anymore, then she had them all stand with bent knees until they couldn't do that anymore.
Then she asked the Class, "how do your arms and legs feel?" That is how weak Carson's arms
and legs feel all the time. I thought it was a great demonstation.
Hope that helps with keeping it simple.
