Ted,the main thing to remember when you have a Health problem is NEVER give up,I have seen too many people have health problems and just give up!I can tell from your post's you not only still have a Sharp mind but a very knowable one about Race-Cars as well.Find you someone who shares the same interest as you,and is willing to do it your way and is a winning driver.If you are going to put someone in your car make sure they have what it takes to Win races,unless they bring some $$$ to the Team!
PS no matter how good your Doctor is,FIND ANOTHER ONE THAT IS AS GOOD OR BETTER THAN HIM AND GET A SECOND OPINION!!!!Don't let your Doctor send you to another one for a 2nd opinion,find another one on your own!
