I am in generally good health with no known chronic conditions. As a youth and young adult I suffered from many sore throats and upper respiratory infections, more than normal. Since age 45, these are very rare. I have never drunk alcohol, smoked, or used caffeinated beverages. I am six feet tall but persistently thin, never more than 155 lbs, regardless of how I eat. Never actually underweight, however. I am easily troubled by skin issues, such as contact dermatitis, hives, pimples, canker sores, and psoriasis. I would like to better manage these by learning how others have succeeded.
