Hmm, the list of habits wasn't even that bad: Don't smoke, drink little, keep a BMI of 18.5 to 24.9, exercise 30min per day, have a diet in the top 40-percentile most healthy. These seems like feasible habits. Sure if you're overweight, smoking or drinking a lot changing the status isn't easy. But you don't have to go vegan :)
Once you start it's a slippery slope to full on vegan. You will look at meat and dairy not as food but as liabilities to you and your earth.
Then it's just kinda depressing. Here you are in an alternate universe with hope and love and beauty while your friends and family stuff buttered bred muscle into their mouth and complain about all their health issues brought about by eating meat and dairy. These same friends look at you with concern for your life decision to not eat meat or dairy while you look at them with concern for their decision to eat meat and dairy.
You research it and realize the meat and dairy industries lobby and get our money for their ad campaigns. got milk beef. its whats for dinner pork. the other white meat
For the last 70 years they have been programming us that this is how food should be three times a day, every day. We will look back on the cruelty it takes to buy meat on foam wrapped with cellophane and our grandkids will ask us how we disassociated ourselves enough to take part in it all. Why didn't we shout from the rooftops that we are destroying ourselves, our world, our dear sentient animals?
