I like Colpo alot but he is dead wrong. I have no idea what data he is sourcing because over all endurance athletes die a lot earlier. Take a look at this study that has all the professional sports teams i work with really re evaluating what they are asking them to do.

Aims - This study examined the cardiac structure and function of a unique cohort of documented life-long, competitive endurance veteran athletes (> 50 years). Methods and Results - Twelve lifelong veteran male endurance athletes (mean ± SD [range] age: 56 ± 6 yr [50-67]), 20 age-matched veteran controls (60 ± 5 y; [52 - 69]) and 17 younger male endurance athletes (31 ± 5 years [26-40]) without significant co-morbidities underwent cardiac magnetic resonance (CMR) imaging to assess cardiac morphology and function, with CMR imaging with late gadolinium enhancement (LGE) to assess myocardial fibrosis.
Results - Lifelong veteran athletes had smaller LV and RV end-diastolic and end-systolic volumes (p0.05), but was significantly associated with the number of years spent training (p50 miles) marathons (p
Conclusion - An unexpectedly high prevalence (50%) of myocardial fibrosis was observed in healthy, asymptomatic life-long veteran male athletes, compared to zero cases in age-matched veteran controls and young athletes. This data suggests a link between life-long endurance exercise and myocardial fibrosis that requires further investigation.

J Appl Physiol (February 17, 2011)Diverse patterns of myocardial fibrosis in
lifelong, veteran endurance athletes

They compared age cohorts of those who did life long endurance training and those who did regular exercise. 100% of the endurance athletes had myocardial fibrosis. 0% in the other group. I can tell you this one paper has all athletes and trainers rethinking their ideas on how to train. It also explains why cardiac death is the number one reason that endurance athletes die.....and cancer is two.
This is will be a focus for me to write about. I think its critical that this paper get read by every paleo athlete. I hand it out to all my patients who fit the bill.
Edit: by Dexter to show study.
