I think this is a lot more common than we realize. I've noticed some men as they age seem to prefer DIY solutions over pre-bought solutions. I think it might be a mix of enjoyment, or self-satisfaction from coming up with a new solution, or remnants of an old habit they developed out of necessity when younger.

I live in a rural area myself and it's not unusual to see a pick up truck with DIY elements on them such as a wood bed rack, or wood bed cap. Usually this is a dead give away of an older gentlemen driving it. My parents own a pick up truck that had an older gentleman as a previous owner and it has a DIY wooden center console in it as it did not come with one from the factory. Ford sells a center console as an option for some of them but I guess he preferred to build his own.

I fear this will be me in 40 years.
