I mentioned that for all three kinds of lives -- the pleasant life, the good life, the meaningful life -- people are now hard at work on the question: Are there things that lastingly change those lives?
Jeg nævnte at for alle tre former for liv,  det behagelige liv, det gode det, det meningsfulde liv,  arbejder mennesker nu hårdt på spørgsmålet, er der ting der ændrer vores liv for bestandig?
