Happiness is not immortality, big fish and meat, or power. Happiness is the fulfillment of every small wish in life. You have something to eat when you want to eat, and someone to love you when you want to be loved.
Happiness is not about being immortal nor having food or rights in one's hand. It's about having each tiny wish come true, or having something to eat when you are hungry or having someone's love when you need love.
