My grandfather died of ALS a few years ago in his late 70s. It's sad and ironic, but he was a runner until the last three or four months of his life, when the disease rapidly crippled him and took his life. He was the sort of guy you would expect to live well into his 90s: He ate a perfect diet and exercised like he was 35. At the time, my grandmother was battling bone cancer, and we were quite concerned that my grandfather would be depressed living for multiple decades without his wife. Unfortunately and surprisingly, he died almost two years before my grandmother.
