>>13904547>makes you wonder There are certain signs that show the types of poisons that lead to the end of life. Cyanide blocks the messages from the brain to the muscles by changing body chemistry in the central nervous system. Even the "involuntary" functions like breathing and heartbeat get mixed neural signals. It is a painful death, breath coming in spurts. The other muscles spasm, limbs twist and contort. The facial muscles draw back into a deadly grin, called "cyanide rictus."[30] All these telling signs were absent in the Jonestown dead. Limbs were limp and relaxed, and the few visible faces showed no sign of distortion.[31]
