I don't just mean the valve body, but the little nubbin on the threaded
shaft - if you're cack-handed, which I have been known to be, you can
easily use that nubbin to bend the shaft badly.

I don't normally take my wheels off to pump them - I do far more weekly
maintenance inflation than post-flat inflation.

I don't anymore, but I used to before I worked out how not to. I think
it's reasonable to say that _in this respect_ the Presta valve is
inferior, because other valves are harder to break.
