"Avoid cold and flu...some say obsessive"
Haha! Me too. I'm a bear! I tell people in no uncertain terms when we make a date to get together, if your kids are sick, please do me a favor and do not come. My body cannot tolerate colds and flus like normal people. This works well. I've trained everyone, and they call if they are unwell and ask if they should come or not. That is perfectly fair.
I look at it this way. 1 in a thousand will get this. Only one. that one person carries the torch for the other 999, because statistically someone had to get it. Each of us is that one. What ever small thing can be done to keep us as well as possible is fair to ask. It's Ok to have family members get flu shots (though I am sure some will say mercury! toxin! not natural...Ok don't do that if that's you) or to take airborne or occincillconnium (sp?) or other natural remedies to prevent colds and flu...
It's fair to ask people to do anything within your own code of OK things to keep you well.
dx since '93 MS definite since 91. First atttack 86. I do not/have not eaten gluten fat sugar, dairy, allergens, intolerances, and take Copaxone since it came out, as well as many supplements. My hay fever is well controlled. SPMS this year 05. I could jog still in 99. Progression happens, I credit being able to jog at 6 years after diagnosis to healthy habits. I credit today's level of function about edss 5.5 to MS.
