I've read several times in recent years the idea that's supposedly been backed by studies that hard running over a lifetime is actually bad for the heart (wear and tear) and reduces life expectancy. Obviously elite runners are way healthier than the average Joe to being with, but they also train (or trained for a long period when they were competitive) way harder than a hobby jogger.
So I decided to look at the age of deaths of the top Olympic champions, focusing on the 800m. This is what I found :
All the 800m Olympic Champions from 1956 to today are still living (Tom Courtney is 84, and Peter Snell is 79).
Mal Whitfield, the champion in 1948 and 1952 died aged 91. John Woodruff champion in 1936 died aged 92.
Albert Hill and Douglas Lowe, British winners in the 1920s, died aged 79 and 78. When they were born (in late Victorian England) the life expectancy was less than 50.
Only one gold medalist in the last 113 years has died 'prematurely' (Tommy Hampson 1932 died aged 57).
All the medalists from 1928 lived until at least 79 (silver medalist reached 88). They were all born at the start of the 20th century when life expectancy for men was under 50.
The age of deaths of the 6 medalists from 1920 and 1924 were : 79, 76, 53, 78, 85, 70
1896 : Edwin Flack (61)
1900 : Alfred Toysoe (27)
1904 : James Lightbody (71)
1908 : Mel Sheppard (58)
1912 : Ted Meridith (66)
1920 : Albert Hill (79)
1924 :Douglas Lowe (78)
1928 :Douglas Lowe (78)
1932 : Tommy Hampson (57)
1936 : John Woodruff (92)
1948/52 :Mal Whitfield (91)
1956 : Tom Courtney (1933 - 84 living)
1960/64 : Peter Snell (1938) 79 living)
1968 : Ralph Doubell (1945) 72 living
1972 : Dave Wottle living 67
1976 : Albert Juantoreno living 67
Taking a cursory look at some other distances, it seems the same pattern. For example, the 5000m in 1924 :
Gold: Paavo Nurmi (76)
Silver : Ville Ritola (84)
Bronze : Edvin Wide (100!!)
