Lol, you made the mistake already.
Life is not about healthy. Your life span is determined the second you exit your mother's womb. Your genes have already determined how long you will live. The only things that matter are the extremes.
Extreme exposure to radiation and chemicals, alcohol, tobacco, hard drugs, and extremely poor diets. That is what may take years off your life.
The idea that eating a depressing diet of veggies and other bland foods will actually ADD years on to your life. You are fucking fooling yourself.
But by all means, keep up the disillusion. Healthy living is moderation. A long life is healthy living and good genes, plain and simple.
