Exactly how many threads and forums are you going to raise this issue in?
These studies have been discussed at length in various of our forums. If you use the search function you will be able to find those discussions, and add to them if you wish, rather than starting multiple new and redundant conversations about them
For the record, the studies related to athletes undertaking extreme endurance sports. Professional cyclists doing huge mileages, ironman triathletes, multiple marathon runners. They have no relevance to most amateur cyclists. And even when dealing with the extremes, the authors acknowlEdged that lifetime vigorous exercisers typically lived longer, and retained good health longer, than others in the population.
