Phil. Interesting to see that list. You hit the nail on the head in your last post. Running a world class marathon is hard work and other than maybe 3 on your list I guess it costs people money to do it vs earning from their talent elsewhere. No mystery to why we have no strength or depth.
Selbs. Gutted to hear about the SF. If it wasn't for bad luck you'd have no luck at all. Makes those still knocking it out in late 40s and 50s even more impressive.
Odd business with medal sales. I can't really think why someone would buy one? And if you could be arsed but wanted to keep your souvenir the smart thing is to sell immediately and then buy one again in a few weeks when they can be had for the price of a cup of coffee.
