Dang, well I did my own math, and it gets confusing down
there to the left of the decimal point. I like your answer better than
mine. Either way, they're not going to crush each other getting through
the catheter. By the way, if multiple posts start showing up about this
Hickman problem I've been having, my email address got changed without my
knowledge, and I was trying to post for several days without success. I
hope all those chickens don't make their way into the list now that I solved the
problem.
