More downers from the New York Times--turns out, drinking hot water from the tap increases exposure to lead poisoning, as hot water tends to dissolve contaminates from within your own plumbing:
Lead is rarely found in source water, but can enter it through corroded plumbing. The Environmental Protection Agency says that older homes are more likely to have lead pipes and fixtures, but that even newer plumbing advertised as “lead-free” can still contain as much as 8 percent lead.
Scientists emphasize that the risk is small. But to minimize it, the E.P.A. says cold tap water should always be used for preparing baby formula, cooking and drinking. It also warns that boiling water does not remove lead but can actually increase its concentration.

Did you get all that? Boiling hot tap water concentrates existing lead, so for cooking, hot beverages, and particularly for folks making formula for little ones, run and boil COLD tap water, please! Thank you!
(Seems I'm going through an precautionary, apocalyptic phase of sorts...this is my way of loving you, dammit!!)
