Wow Greta! I have read about families having MS so it's not unheard of. I hope the conversation with your brother goes well.
The good thing is you are all not symptomatic. I guess that's a blessing in disguise. (you know me, ever the optomist! You can smack me now!)
Let's hope you all stay that way. Maybe if you do decide to have a kid, Jim's genes will be stronger than yours! Ok ok, I will stop now!
It's the drugs...honest! You know I love you Gretata!
