Sean and I were on the way home after school today and I asked him what he learned in school today... he said, "Mom, do you know that your heart bumps faster when you are running?"
"Yes, your hear does pump faster when you are running."
"And it bumps slower when you are just not moving..."
"You are right... it does pump slower."
After a moment to think, he added, "Your heart bumps blood!"
You are so right Dr. Sean!
