Plant based diets - they are the kind of thing you only attempt when there is a compelling reason or strong momentum to want to change. I have been 90% committed to pursuing being a vegetarian of late, and have noticed improvements in energy, clarity of skin and mind, uplifted mood in general, and savings at the supermarket. It's only been 4 weeks, and now I can stand back and assess the sheer amount of meat I was consuming morning, noon and night. Having said that - old habits die hard and cheat meals are in order. Only so much you can cook with lentils or have another bowl of dahl soup (don't get me started on the gas and bloating). I go the caesar salad with prawns, prosciutto and egg once a week and it is a godsend!
People are like aircraft; when we are brand new we can do and go anywhere we please. And people want to ride us all the time! As we age, we require heavy C and D grade maintenance checks, a few re-fits (hopefully not in the style of Qs' enhancements), break down a lot more and end up frustrating people. Knocking meat off your shopping list is a great way to claw back a few years and feel more alive within yourself, harking back to our golden era. This should be tempered with the wisdom that we can't play/party/smoke/drink/eat meat like we used to in our 20s without their being a coughulative effect on our health overall. It will give you a few more productive years in service before we are all shipped off to Victorville. I have an exception to that rule -- when i do fly business or first class I will eat and drink anything i want as it is a privilege and something special. Life is a one way ticket, so best to live it your way and what makes you happy. See you in the graveyard!
