But listen this might happen to me later
I had a friend who would never go anywhere without a little snack in her bag.
Some biscuits or crisps - a bar of chocolate maybe.
"It's the thought of being hungry" she explained. "I can't bear it. What if I was stuck somewhere with no food anywhere and the hunger struck me?
"And if I know there's going to be a big gap between meals, I'll stuff myself so that I'm as full as I can possibly be to reduce the chance of hunger later."
I was really surprised at the time but now I find that this is more common than you'd think. "Oh yeah" people have said to me. "Preventative eating. You know eating more on the off chance you might miss a meal".
I know diabetics have to carry snacks around with them - but the rest of us? Is this something you do too?
