Two recent tragic news events – Sunday's fatal shooting at a St. Louis-area church and last month's chimp attack on a woman in Connecticut – are being pinpointed possibly to a similar cause: Lyme disease. Relatives of the church shootist say that he never was the same person after being bitten by a wood tick and contracting Lyme disease a decade ago. And the pet chimp that mauled a woman in Connecticut was also suffering from Lyme disease. USA Today ties together the two stories right here. I admit I didn't know about this dimension to Lyme disease until seeing this story. I was at first skeptical about such a cause/effect relationship, but am now willing to consider it as a possibility. What do you think?
