Another word about Garlic

I posted instructions on how to use garlic Here but I just wanted to pass on some information I have been given.

Whilst garlic adds a lot of flavour to many dishes, it does tend to have anti social side effects.  I am led to  believe by a knowledgeable source however, that if you cut the clove in half lengthwise and remove the centre fibre, which is sometimes green it will remove most of the pungent garlic odour  which hangs around for ages after eating it.
I have tried this but I can't vouch for the veracity of the statement as one cannot smell it on oneself, and as a general rule it tends not to be noticeable on another person if you also have consumed .
