... Secret to life and agelessness. Taken from my studies in anatomy. There is a chemical called cortisol our bodies produce in times of stress that keep us from dying immediately. This chemical is also responsible for cellular degradation and a lot of the free radicals that cause aging. To prevent this chemical from being produced, we must free ourselves from all stresses. This includes anger, fear, jelousy, depression, guilt, and all negative thoughts or feelings. Physical stress like pain, injury, illness, disease, and over exertion is also responsible for the release of cortisol. 
Emotional stressors are more likely relieved from a realization of the imperfect nature of all people and the forgiveness you give to yourself and others. Always forgive yourself first. Then pick yourself up and forgive others. For more information on the secret to life, just ask..
