You must have excellent coordination. Others, like me, are clumsy. Its certainly not wanton disregard that results in me dropping my phone. It just feels like it slides out of my hands sometimes.

I'd have to live my life in an unsustainable state of vigilance and care to not drop things.

Heck, even when I think I'm being careful (eg carrying a very full mug or glass), I'm liable to focus on what I'm doing to the point of messing it all up due to lack of awareness (eg keeping my glass nice and still until I bump my elbow into the door frame and spill some of my drink).

It also does not seem to be improving wit age.

I drop my phone occasionally. I don't think there is much evidence that I am uniquely non-clumsy. Phones aren't that fragile, particularly these days.
