Falls are VERY HIGHLY correlated with the last year of life.
Your sauce, Highest Ranking Anon:
The mortality rate for falls increases dramatically with age in both sexes and in all racial and ethnic groups, with falls accounting for 70 percent of accidental deaths in persons 75 years of age and older.

At the 70% level, that would make falls more than twice as lethal as the other factors…combined. So…I didn't say 'leading' cause of death…just VERY HIGHLY correlated with mortality. If you're old…stay fit…falling is bad. Breaking bones in a fall is really bad.
