I think everyone has a Normal and an OK, Now You're Being Crazy internet threshold. Checking your e-mail is normal. But Googling holistic remedies for cat eczema or the location of Robert De Niro's summer home or the calorie content of a medium-sized apple or the middle name of Kurt Cameron's youngest child? OK, now you're being crazy. I always try to stop myself before the latter occurs, but I am rarely successful.
