At least that is what my doctor told me. However, back to that old favourite Mars Bar. Named after its inventor, Mr Bar, these have been around for some 80 years. No, I don't mean the ones you'll buy from here as that would make them a little past their sell-by date.
Mars Bars are lovely when cool, yet horrible when hot. Eat one that has been left on a car seat on a hot day and you'll know what I mean. Have cool ones and they'll be a snacktime favourite. Hot stringy caramel is a no-no in my book - mainly because the pages get stuck together.
If you have not tried them before I would recommend buying used or renting first, just in case.
