is it the same like getting hit in the chin? like wouldve i blacked out to if i got hit in the chin or is it that the top of the head is weaker and alot of people cant take hits to the top of the head. because ive taken good shots to the chin before and never blacked out or got wobolly legs.everything just went slowmotion for like half a second but nothing drastic. but when i got hit in the top of the head i blacked out for a while is it normal? and also how do you know when your hitting the heavy bag hard and firm and with power when you hear a loud snap or when the bag moves. thank you.
