Interesting, isn&#x27;t it?<p>I swim (since I was 13, that is &gt; 37 years). I also don&#x27;t train like a maniac any more but simply try to improve my style and keep my fitness. But I hardly meet anyone in the pool half my age who has the slightest chance to keep up. This is not meant as boasting at all. The good non-professional athletes seem to be &gt; 40 these days.<p>Is that a sign that we don&#x27;t have good trainers? Or do others only start to work out after the doctor starts to pale while looking at the blood analysis?
