Just to clarify, 'cos I've had PM's... ::)
I don't eat meat, and started to phase meat out of my life from age six: by the time I started secondary school I'd eradicated all meat & the vast majority of animal related byproducts (gelatine, lard, rennet, isinglass, E-numbers etc) from my diet. I'd say I was a fully-fledged veggie by 13/14, that's around 20 years thus far...
I personally believe that meat is not a necessary dietary component, however if folk want to eat the stuff, fair enough... I'm not a militant veggie by any means, and if someone is educated as to the practices of the industry and still choses to consume meat I'm not going to argue... Personally, I'd rather 'meat eaters' understood how their food was produced and made informed choices than preach the 'meat is murder' viewpoint. Hence my original comment which began: "If you eat meat..."
Out of interest, has Mrs Simmo changed her mind?
