My best friend is a nutritionist, and has seen a lot of people who have gone vegan, and ended up with serious health problems. People need to do their research, and no what supplements to take. Paul and Jason eat mostly processed and package foods. So who knows what's in it. They can't claim it's healthy, just because they add some bits from the allotment.
Paul sounds like a fifty fags a day habit. The dark circles round his eyes could be his liver. Neither of them look healthy.
Bet Pauls on the biscuits and cakes when Jason's at work, then nips out for a cheeky kebab.
