How many people with heart conditions have succumbed to the stress that can result from trying to open a plastic “clamshell” package containing some newly-purchased item?  I assume these difficult-to-open packages are intended to curtail shoplifting, but I still think there should be a requirement for warning labels that would put these packages into the same category as roller coasters:

“WARNING!  Before purchasing this item, please note that you should be in good health and free from high blood pressure, heart, back or neck problems, or other conditions that could be aggravated by multiple futile attempts to open this package. Expectant mothers should not attempt to open this package.”

or maybe,

“Requires 2 AAA batteries and 1 heavy-duty pneumatic reciprocating ‘Mini-Jaws-of-Life’ package opening system (not included).”
