Gratitude is the most important of all human emotions.

Every stress leaves an indelible scar, and the organism pays for its survival after a stressful situation by becoming a little older.

Unlock your natural drives by doing what you enjoy.

What makes me so certain that the natural human lifespan is far in excess of the actual one is this. Among all my autopsies (and I have performed over 1000), I have never seen a person who died of old age. In fact, I do not think that anyone has ever died of old age yet. We invariably die because one vital part has worn out too early in proportion to the rest of the body.

If you want to live a long life, focus on making contributions .

Man should not try to avoid stress any more than he would shun food, love or exercise

To remain healthy a man must have some goal, some purpose in life that he can respect and be proud to work for.
