I wear monthlies, but when swimming I swap for dailies, chuck them right after and wear glasses for the rest of the day. I feel safer that way. But I don't take any kind of precaution in the shower. I didn't even realise there was a risk there.
One more thing to live in fear of besides climate change, cancer, drug resistant bacteria, nuclear war, terrorism and the singularity. Yay.
Should I feel better or worse that it's far less likely to affect me than any of those things?
