They do, so of course they're designed to minimize that. Tension will increase
the natural frequency of the cable, hopefully well above the vortex shedding
frequency.

I wouldn't expect an even distribution of names, so if John Smith weren't
popular, something else would be. Also, if John Smith has a lot of kids, then
then you'd expect a lot of Smiths, some of them named John. Looks like it's in
decline around here though. Your results may differ.
