How much Hydrochloric Acid is produced in the stomach?

A friend put me to test over this. A little detective work produced a lot of reading. Here are the final answers to this problem:

1. "During a meal, secretion of gastric juices (containing HCl and pepsinogen) increases from a few mL / hour (the usual values between meals) to almost 1.5 L."

2. "GASTRIC JUICE is produced at the rate of 1500 ml/day composed of 5600 mg. HCL, 1120 mg. Potassium Chloride and 175 mg. Sodium Chloride."

While we are at it, how about this:

"Does the heart stop when we sneeze?"
