Okay, everybody knows strength peaks in the early 30's. Everybody knows that the more you do something and the smarter you are about it the more one conditions oneself to perform the activity. This is apparent in virtually any activity and most pertinently here in muscular strength and CNS efficiency. This is all common knowledge and grounded in fact.
Old man strength - which I'm guessing means that strength keeps increasing regardless of activity enabling 'old fat men' to throw around kegs like nothing is the issue.
Obviously if you are throwing around kegs at 50 years old, you've been doing it for quite a while - not a new position on the corporate ladder for you. There's an obvious adaptation and training effect. Plus, there is a population and survivorship bias in that anyone who can't move kegs around the floor easily doesn't get hired and those that loose this ability are no longer useful to employ.
This is all black and white - as a matter of fact, I can't even believe I'm sitting here involved in discussing this. There are rational explanations for all of these things. There is also an explanation for 'old man strength' in that it has no grounding whatsoever and any supposed witnessing of it is really a composite of other very commonly known factors that I went through an explanation of.
Given that this is a training board and that there is already more than enough misinformation and outright bullshit spread over the weightraining world to rationalize a circus size pair of stilts, there should probably be some effort to stick to science, facts, and logical methodology rather than using voodoo-like terms and explanations for commonly known and well established processes.
