I echo what the majority have said...do it, without reservation, hesitation or remorse. I have ridden motorcycles most of my life, and took a break from riding for a couple of years when I was diagnosed.
Two years ago I was convinced that I would never ride again because of my leg and neck problems until a friend suggested that I should give it a try again at least, before I said " I can't".
Thank goodness for him; I DID try it again, and found that " I could". Ultimately, it led to chronic motorcycle-itis...I bought my dream Harley last year.
A Harley for me...a sports car for you...the memories of even one day of a dream fulfilled will make it all worthwhile, and they'll never diminish. Do it; you'll be so glad you did
