Nail Damage

I nearly wept this morning when I discovered that my fingernails seem to have become slimmer. More finger flesh is exposed on the sides. The nails are perhaps more convex. This change does not sit well with me. I assume it has something to do with a lack of strong pressures beneath my fingers. I am typing and mouse clicking when the pressures beneath my fingers from tree climbing or door slamming might have kept them wider, and in my mind, proper.
