I am not a medical doctor, but I believe carcinogens cause cancer from second hand exposure and from couples who use regularly while making babies: marijuana, tobacco, and alcohol, cocaine, heroine, microwaved food, meat that uses steroids or long periods of sitting and transport through freezing and unfreezeing multiple times before eating. Not using enough salt on animal proteins. Also I do not think high levels of caffeine is good either. Proper rest and increased motion to make us tired enough to sleep is a better way to create energy, as well as a positive optimistic character and joi de vivre (joy for life). Carpe Diem: seize the day, and learn a little each day. God loves you, and Mama Mary loves everyone especially people who love the nativity from anno domini. Christmas Day has nothing to do with reindeer and Chubby men in red suits. Christmas Day is about God and his Bride (mama mary) bringing all humans an opportunity to invite loved ones to eat and play in heaven after their time on earth.
