I posted earlier that I have accumulated a lifetime supply of pens so, when I use them, I try to use them up. The pen I'm using now is an old Bic "crystal" ball point whose cap has dissolved in the mists of time. What amazes me about this old workhorse is that the ink level has sunk below the visible barrel for several days (not that I'm writing all the time, mind you) yet it keeps on writing. I wonder how much ink there is in that little metal nib end of the pen.
Yes, I realize how inconsequential this post is but such inconsequentialities (What?! -Ed.) are the stuff of life.
