Dear Mr Copetas,

That depends on many factors, which include diet, daily physical activity, and so on. In your case, (as you eat at Anna's Taqueria everyday), you could breath between 25 and 50 liters (i.e., 10 to 20 gallons) of your own gas. I will forward your question to the Risti Thum, Head Statistician at the Hash Institute.

Best Regards
Giulio Gambarota
