Why do men fall off roofs and ladders more after they are 50 or so?

 I think I can speak to that. Men often believe they are still 25 and are immortal and can to anything until they wind up in a hospital from overestimating their abilities. But, I think the main factor is when 

you are younger you are usually thinner going up on ladders and roofs (usually both) but above

50 men tend to have gained weight and so this makes them "Top Heavy" and harder to keep their 

balances in many different situations. So, if you make a mistake on a roof or a ladder you wind up 

often in the hospital. I have one friend who fell off his dome house and broke most of the bones

in his body. However, with a cane he can still make it up to Horse camp on Mt. Shasta.

Another friend of my father's and mine fell off a roof in his 50s or 60s and was dead a few months

later partly from falling off this roof and his internal injuries that he might not have addressed

properly because men were much more macho like that in the 1960s and early 1970s because he was 

of the generation of my father's that was a younger man during world War II. So, "A man's got to know

his limitations at every age or else he is soon Dead."

An unrealistic assessment of your abilities (at any age) can result in your maiming or death.
