Ear Hair - See the nose comment
Gas - Tums, Gasx and acidophilus.... make them part of your life.
Heartburn - I eat a high protein diet so I never really have heartburn.
Other Problems....the aluminum pins in my hand and knee get cold in the winter and fuckin sting like hell on some days but they've been that way forever...
