For my own future reference

Having stubbed my left big toe hard just before going to Paris in October, then run over it with the wheelchair a couple of times while there, it was just a matter of time until the inevitable happened. The nail and I finally parted company last night.

At least 3 months of nursing the semi-detached flappy nail means that there is already about 4-5mm of new adhering nail, but plenty of exposed nail bed still to regrow.

This is going to make walking, driving and exercising a real pain for months to come. Sandals are the answer around the office, and a prosthetic nail (plastic over foam over elastoplast) makes some trainers tenable for driving; but it's not really sandals weather, not are they great for cycling; and big trainers don't really do for workouts.
