I'm not sure I buy the "risk->stress->pets" connection. In my own experience, anecdotal of course, people who take risks do so because risk-taking doesn't stress them out as much as it would other people. But your point is still valid. The conventional wisdom on why risk-taking people might be more prone to toxoplasmosis in the first place is that they're more likely to eat undercooked or other ill-prepared meat, which is actually a much more significant risk factor for toxoplasmosis than cat ownership.
