I have BPs and have had several bites including my 3000 gram plus female who thought my hand was a rat and was determined to eat it until the mouthwash came out. She was not planning on letting go ever. But all in all.... I've had paper cuts that hurt worse. Maybe some day you'll join the "i've been bit club" and it wont be so scary anymore.
Cant say much for retics though... I wouldnt wanna be bit by one of them.
