Sardines - A Health Hazard

Some say fish is good for your health, I disagree in this instance.

After decades of practice, why can we still not get a tin of sardines open without either having to use pliers or cut your hands on the metal that is so difficult to peel off?

There must be people out there who design these tins that is having a laugh. Well the laugh is on them, I refuse to buy tins of sardines anymore as they are a health hazard! One lot of bad luck I avoid now every time.
