Naga (Bhut Jolokia) Beef Jerky from a company called Chilli Wizards in Yorkshire.

I ate the whole 50g bag and couldn't feel my mouth or lips for about two hours afterwards!

Chillis are supposed to release feel good endorphins into the brain and act as a natural anti-depressant.

I best eat more of them!

Right you are. Here's a couple of little bits taken from a site called “Chilli World” –

There is a reason why we go on eating chilli even though it "burns" the tongue. When nerve cells release substance p, the body produces chemicals called endorphines - and these act on brain cells in the same way that opium-derived drug morphine does. As a result, you feel good.

The pleasure/pain reaction to peppers is said to have a psychologically beneficial effect and nutritionally peppers contain lots of vitamin a, b and c, as well as magnesium, iron, thiamin, riboflavin and niacin.

Peppers are addictive. Peppers contain capsaicin, a natural chemical that sends a burning sensation from the nerve endings in the mouth to the brain. The body defends itself against this pain sensation by secreting endorphins, natural painkillers that cause a physical "rush" - a high that keeps us coming back for more. So indulge your pepper cravings, and rest assured that you will soon build a tolerance.

There is no evidence that eating too much chilli is unhealthy, or that it causes ulcers. In fact, capsaicin is used in anti-inflammatory creams to treat ailments like arthritis and shingles.

So yeah, chillies = Good!
