Thanks, Figgy!
Actually, I've done a little research since my previous posts...
There are plenty of heart "conditions" you can have and still get a private pilots license. As long as you haven't ever had a heart attack. One site I read listed 9, although mine wasn't on the list and I haven't researched it specifically, so I'm still not sure.
However, I did find out that you can still fly a plane even without a pilots license...as long as there is a licensed "pilot in command" on the flight anyone can fly a private plane.

I'm assuming they would have to also be in the left seat, but, the article didn't specify.
