I can believe the farmer story. It's amazing what a little adrenaline can do in those situations. Like the hiker pinned in the rocks, amputating his own arm at the elbow to free himself. Those things are so far removed from our everyday lives that they seem incredible. And, well, they are.
The bodybuilder & 7-footer comments made me think of The World's Strongest Man competition I watched earlier this winter. There were some huge contestants, 6'7" 400+ lbs of muscle. But the winner was a shorter barrel-chested man, Serbian I believe. He basically won it all at the squats contest. His shorter legs meant he didn't have to move the weight as far.
 
ref strong man some years it favours the little guys, some years the man mountains. Just depends on what they chose.

As for the guy who cut his own arm off, he was there for some time before he realised it was his only hope. That's not adrenaline, that's simple survival at play.

Type II muscle fibers.
Power lifters have a low limb/length ratio : relatively long torso, short legs/arms, mainly type II muscles.
Bill Kazmaier, Jon Pall Sigmarsson, Zydrunas Savickas : low ratio body types.
Basketball players commonly have a high ratio : predominantly type I

(Up till my late 30s, I used to lift a car for a flat tire exchange, saves time and doesn't damage the body underside. Untill I had to hold one for five minutes because they couldn't get the spare wheel on the hub. While standing in mud, ended up with serious cuts in my hands. 6'2'', but I don't fit in cars like a Jaguar XJ, ceiling height is 2 inches short)
 
Actually, that case I saw covered on Discovery Science, practically the only TV station I do watch sometimes. The boy was definitely a small runt, and he said he had no idea how he did it, all he remembers was being afraid that his uncle would die if not rescued soon. They were alone, so he was all there was, it was either him or nothing. There were very clear shots of his uncle's chest, which while not completely squashed, had clear marks of being recently squeezed (bruises, small cuts, etc). Doctors certified that he was brought in to the hospital and after treating him and measuring the truck, the two coincided very decisively. Small traces of the man's blood were found on the bottom of the truck courtesy of the sherrif's department. They established the two were alone and also found the marks of hands, by measurement established as belonging to the boy, on the lower side of the front bumper, which was itself bent showing it had recently been used to support a large weight.

I'd say that was pretty convincing forensic proof of what had happened. The boy was the first to state that he could not do it just like that, at will or on demand. Fairly obvious it was tremendous fear which mustered for for him much more strength than he usually or normally has.

Some people just don't believe in anything beyond their personal education and experience. This is type of person is sometimes called a
'rational robot'. They will go out of their way to 'prove' that someone else is a liar, or that something is impossible. It is their problem, not the topic they are challenging. I try to keep an open mind about such things.
 
The pursuit of audio quality has changed in recent years. Originally, it was getting performance out of existing tube circuits, with little regard for really high quality connectors or cable. It seemed to work well enough 50 years ago.
Then solid state came in, and the parts actually got 'worse' in some respects, and audio got worse, rather than better for several years.
Finally, we made an all-out effort to use the 'best', nearly mil-spec parts, coupled with new and 'exotic' (for the time) topologies that gave the tube equipment a close competitor.
Over the years, we have found dozens of 'improvements' that make a difference, including: better resistors, capacitors, circuit board material and layout, connectors, wire, enclosure, diodes, transformers, etc., etc. It is interesting to see mid fi manufacturers trying to use our 'improvements' of 20 years ago, in today's designs.
The latest direction in audio improvement appears to be better software, i.e. hi res digital, quality vinyl, etc.
However, another approach is being pursued in 'tweaks and mods', including some quantum mechanical based parts that appear to improve the sound in many cases. Why some of these QM upgrades work is still not well understood, but we use them anyway in order to get the best sound quality.

Same with cars. What is cutting edge in F1 today will be in the Toyotas and Fords of tomorrow.

What component of 40 or 50 years ago would you say simply could not deliver anywhere near todays subjective quality ? Would it be speakers do you think ? Or source components (I'm thinking what the average guy could go and buy at the time).

If you could go back 50 years and take one 'component' (a pair of speakers say) back with you that could transform what you had back then, what would it be ?
