Sorry to hear about your friend Monsieur.
Since learning that the WT religion is a scam, I have come to realize how precious this life we have is. I think about my own mortality and that of the ones I love. I never gave much thought to dying young, now I see it as the tragedy it is.
When you are a JW life just passes by without really being appreciated. Some JWs almost hate this life because they believe a much better Satan free life is just around the corner. Like prologos said, we should live this life the best we can, it is the only life that is guaranteed.
What is that saying.... 'Keep looking for answers, beware of those who say they have them'. Something like that.
