I've written a computer program which beeps, then beeps after 10 sec, then beeps after 11 sec, then beeps after 12 sec, etc.
I tried the following "experiment" on myself: do only one breath between the beeps, so slowing breath until I can't do it.
After finishing this "training" and starting to breath normally again, I felt enormous "freshness".
Is this experiment safe for health? How does it influence health?
