A Whole Batch of issues - physical cracking + concept
1: Have you noticed that there is more than one way to crack one joint at a time, so you get multiple cracks from the same joint?
2: Don't you think the aspect of people thinking less of themselves is wrong just because the jointcrack?
3: Since cracking my back, i feel like the upper back and from halfway up, there is always some tension that i want to be released!
With regards to number 1: You get the major crack which has a refractory period and then other minor cracks which you can keep doing consistently.
