Sorry to hear about your mom, but our bodies are outliving our brains because of a toxic food environment that promotes sugar, leading to insulin resistance, diabetes, metabolic syndrome, atherosclerosis, and "diabetes type 3" (Alzheimer's). Individuals are not to blame because this toxic junk is pushed on us by corportions who profit by addicting kids to their products, however--it is wise to understand insulin resistance and metabolic syndrome, in order to avoid them.
