not debatable

If two guys came to my house with competing estimates for putting on a new roof and one was a strapping young lad and the other a slightly feeble geezer, among the things upon which I would not base my decision would be a comparison of their ages since my assumption would be that the person with executive authority is most likely not actually going to climb onto the roof to handle directly the shingle-based aspects of the work at hand. Further, if my choice was instead between two elderly men, I would choose the more well-meaning of the two.
