Answer: This is a fairly vague question. The average lifespan for any area varies significantly based on year of birth and gender, so the range of possible answers is rather large. One statistic, though, is if a child was born in 1996 in Germany, and lived the rest of their life there, they could be expected to live to the age of 73 (for males) or 79 (for females). This is also on par with life expectancies across "First-world" nations.

Answer: Life expectancy of athletes: There seems to have been only one detailed study on this topic, which was published by a group from Finland in 1993:
The study found the following life expectancies, when world class athletes were compared with each other and a reference group of non-athletes "The mean LE adjusted for occupational group, marital status, and the age at entry to the cohort (and its 95% confidence limits) was in endurance sports (long distance running and cross-country skiing) 75.6 (73.6, 77.5) yr; in team games (soccer, ice hockey, basketball, as well as jumpers and short-distance runners from track and field (73.9 (72.7, 75.1) yr; in power sports (boxing, wrestling, weight lifting, and throwers from field athletics) 71.5 (70.4, 72.2) yr; and in the reference group 69.9 (69.0, 70.9) yr." The increase in life expectancy found in athletes was mainly due to decreased cardiovascular mortality and participation in team sports.
