 Folks who do a lot of gardening are less likely to get multiple sclerosis and it's not the actual shoveling or you know getting pricked by a rose it's that there's actually bacteria in the soil right and do those bacteria get introduced that's a theory right we don't have a lot of evidence for it but is it the bacteria that you're exposed to that allow you to not have that bad inflammation. We know this a bit from some of the research that's gone on in asthma and allergies and so there's this famous immunology hypothesis called the hygiene hypothesis and what it means is we grew up surrounded by bacteria rolling in dirt maybe you know my kids did that this morning right and we're exposed to a lot of pathogens a lot of worms things like that before we had sanitation and our immune system was used to reacting to those foreign pathogens right it was trained to do that over millennia right but then over time we've cleaned everything up everything has become sterile right and that's good it helps us with human health but now the immune system is hyperactive right it doesn't know what's for it right and so does this lead to us getting more allergies more asthma because now our immune systems interpret other normal proteins as what we used to have been you know from an immune immunologic subset that have been weighted towards you know fighting bacteria and fungi and and proteasones and helmets and things like that so could it be that we need to be exposed to certain bacterial communities to avoid autoimmune inflammation as well?
