Hi Pierre, thank you for your valuable feedback and sharing your thoughts. I am sorry to read about your brother's situation. I agree that the pain of of some people are relieved to some extent with life standards such as Stephen Hawking managed to live many years with ALS. Howevger, my strong father died in fewer than 3 years after having this uncurable disease. As a family we did our best during that period but recovery was beyond our control. From our human eyes life seems unfair but we don't know what universe has its own vast mind. Therefore, I highlght that our knowledge is just a drop in the vast ocean. Thank you for your kind words about the story. I also like the perspective of Dalai Lama. Wishing you the best.
