I am an admin of our history page on Facebook and so I know we can learn from the past. Gas and electricity have given us all our modern gadgets, but before the development of gas, people had to cook on open fires. That was something of a chore and even today cooking on a modern gas cooker seems like a chore to many people. So we have seen a proliferation of takeaways and fast food joints spreading across the UK this century. We don’t just have fish and chips on Fridays, fast food and eating out has become the norm for many people. Delicious foods zap our reward centres and it is our reward centres that drive us to do most things. We are addicted to pleasure! The smooth delicious taste of chocolate drives us to eat more than one bite and we end up eating the whole bar.
