I don't know why there hasn't been more research, bones and joints are a pretty important part of the body.
I guess the way society works its life threatening stuff that gets priority..
When I got up from sitting down the other day, I got the weirdest crack in my neck/skull.
As I got up, I got a crack like pushing upwards in the left side of my neck.
It felt good, but its completely out of my control, which I hate!
Has anyone else experienced this crack?
Barbados, while scuba-diving etc. ?
As an aside I was popping my knees (don't ask) in my mom's car while my dad was driving on the interstate and knocked the drive shift thingy into neutral… I quickly grabbed it in put it back in drive. Additionally I was popping my neck while my dad was driving my grandma's car and I hit a button that changed the speed from mph to kph. We were pretty scared until we got it back to mph.
Whats so bad about the difference between mph and kph ?
i guess it could confuse them if all the roadsigns were in kph?
Not really as like for running - when your foot hits the ground, it impacts a weight 3 times your body weight.
