Ah, good old popular science purveyor Joe Schwarcz pops up again   Apart from his chemistry being decidedly shaky, we have this gem:

Any excess base in the blood is quickly neutralized by carbonic acid which is generated by inhaling carbon dioxide and excess acid is neutralized by the release of calcium from bones.

Inhaling carbon dioxide? The carbon dioxide component of air is less than 0.04%. You'd never make it in time. Far better to utilise your own carbon dioxide production for the purpose, eh, Guest? Excess acidity is counteracted by an increase in carbon dioxide exhalation. Losing bone calcium for this reason only happens in cases of serious underlying disorders. Perhaps Doc Musket could flesh that one out. We don't want to be turning into rubber people, do we?
