Today's visit to the doctor didn't help

Just come back from my doctor - a regular visit to check on my blood pressure. (It's satisfactory) In our wide-ranging chat I told him that after a several-month pause I'd resumed occasional morning running again, which he approved, of course - and then I said I'd been wondering about the fact that I'm hardly ever ill from anything. The last time I recall actually even having a heavy cold, which had confined me to bed for maybe a single day, must have been a good 15 years ago. He put it down, after questioning, to the fact that I don't meet and interact face-to-face with other people. In fact any 'social life' at all has been completely non-existent since the early 90s. Then I wondered if it also had anything to do with my having been veggie for nigh on 50 years. I didn't expect the uncalled-for mini-lecture I then got on how it was more 'natural' for man to be omnivorous (like himself, he just happened to add) and that as human teeth are designed for eating meat (Designed? By whom?), my not eating meat (and fish) is more of a fluke to my being in good health than anything else. I wanted to riposte that my reasons for being so were purely empathic, in not wishing to partake, just for a few moments of 'pleasure', of the product of another sentient being's pain, distress and probably terror, often after an entire lifetime of extreme discomfort (to put it mildly!) and anguish - but I was so gobsmacked by his little tirade, albeit with a smug smile on his face, that I was left speechless. I left his surgery doubly irritated by his sanctimonious attitude (and it's us veggies who are usually lampooned for being 'oh so superior!') and also annoyed with myself for not coming out with a ready and justified answer to him. I bet that if he'd taken my B.P. at the end of the session he would have got a very different reading.
