Researchers at the National Institute on Aging say their study suggests a link between depression and cancer in elderly people. December 15, 1998. Web posted at: 8:15 p.m. EST (0115 GMT) WASHINGTON (CNN) -- A new study by researchers at the National Institute on Aging suggests a link between chronic depression and cancer among older patients.

Rate this answer: A wolf's bite packs a punch of 1500 pounds of pressure per square inch which is meant to snap an antelope or elk leg in half. A domestic dog even an American Pit Bull terrier can't even measure up to half of that at about 250 pounds of pressure per square inch.
This is interesting, I saw a show on Animal Planet that said the Rottweiler had the #1 bite force, German Shepherd #2, and I believe a Pit Bull was #3 in the Dog world! quite honestly i find the whole research on this topic BS. who can really tell a breed average PSI in bite strength.
