The pain associated with a heart attack differs from person to
person. Many people describe it as a heavy pressure or squeezing
sensation in the center of the chest. Others report a stabbing
feeling. At times the pain may radiate to the left arm, jaw or
back. The intensity of the pain is not an indicator of the degree
of heart damage that may be occurring. Some people don't have any
symptoms during a heart attack.
Doesn't sound very pleasing to me..
The best, comfy way to die for me is to breathe in excess
helium. Or just take loads of sleeping peel and fall off a building
or something.
