Pigs enjoy being around other people and so being alone for long periods of time can cause illness in a Pig. They also like to party and have a tendency to over do it at times. Because they do not get much exercise they also have a tendency to gain weight. A Pig's stomach and intestines are prime spots for sickness because he tends to overindulge with food, alcohol or nicotine. In order to maintain a clean bill of health, Pigs should watch their diets, make sure they get enough vitamins and minerals each day and somehow work an exercise routing into their daily lives.
