My trusty Brompton—a folding bicycle, and the best two-wheeled transportation machine invented—had a few bolts that were stiff and stubborn.
I lived with it for a bit because it only slowed down my folding and unfolding by a few seconds.
But after a month or so, I got fed up.
On my way home I pulled into a corner shop and picked up a can of WD40 for about £3. Two sprays and my Brompton and its bolts were back to what it was like the day I bought it.
I chuckled. Why did I wait so long to solve the problem when the solution was trivial and easy to implement?
