I am a newcomer and have been reading a lot of people' posts about breathing. I got a lot of advice and harvest, but the standard is confusing me. I wanted to try to establish something that could be quantified, so I came up with the idea that when you light a pipe, the force of inhalation should be about the same, if the size of the pipe is not confusing. So my question is, How many times as hard do you breathe when you light a pipe as you do when you keep it burning?
