the obesity is weird in my family, on my mother's side it skips a generation and on my father's side everyone is. When i was a kid I was healthy weight and then after having my kids, i didn't lose the weight. But the children are a healthy weight. The Autism, i think only runs on my ex-husband's side because his child with his new wife has it as well. But with my children it's mild, they are both smart in their own ways and are functioning on their own. For the cancer, no one in my family got the same kind, so there's not one kind that runs in the family. All the ones that had it did not smoke or drink. I get migraines when i smell cigarette smoke, even just a little. I have always had that. But as soon as im away from the smell i am better.
