I try to keep mine on the short side. Otherwise they just break when I'm doing something...

For instance, dealing with snowshoe laces outdoors in real cold weather, I don't need long nails. I also do some art with acrylic paint and just find it easier.

I gave up on nail polish 30 yrs. ago. I actually found my fingers felt cooler....maybe it was being more hyperconscious of the coloured nails/fingers. I do have a cooler handshake.
