Young people dying is sad, but it's also uncommon in the west. My grandfather died at 85. At that age, death can be in the form of almost anything. Complications from fevers, urine infections, the onset of age related diseases. It's amazing just how quickly someone that age can go from a physically and mentally alert person to death. The root cause of all that is ageing. Your grandfather is certainly the exception. Ageing weakens the immune system, it leads to cell death, it increases the likelihood of cancer, it increases the likelihood of alzheimers, it leads to brittle bones and muscle wastage. Chronic diseases like cancer and heart disease are caused by ageing. Yes, sometimes young people suffer from these, but they're exceedingly rare. If you consider it a goal to increase the lifespan of your population as a whole, you change that by targeting the things that affect everyone. 0.6% of all cancers are diagnosed in the 15-24 age group. If that rate was kept up for life to 100, cancer rates would be 6% of what they are now. 55% of people in the same age group are killed in car crashes or by guns (in the US). If you want to save lives, that's where you focus.
