Yeah. I'm as fascinated by the theory as the next geek, but the evidence for a causal connection has remained pretty thin for awhile. The case for lithium in ground water reducing incidence of depression and suicide seems stronger. So if one is worried about toxoplasmosis then maybe they should also be buying pallets of Pellegrino, as it's the most widely available bottled water with the highest concentration[1] of lithium. It's part of how I justify the expense to my spouse :)

[1] It's still only a small amount. You can actually buy lithium water on Amazon with orders of magnitude more lithium, but that seems unwise....
