A longtime neighbour of mine (he's an OAP like me) has a full English every morning and it consists of: two fried eggs, three rashers of bacon, two black puddings, three sausages (usually Cumberland), two hashbrowns, a grilled tomato, beans, mushrooms and three pieces of fried bread. And a pot of tea, of course. He's had the same brekkie every morning since he retired 15 years ago, and he's as slim as a rake. He's at least two stone lighter than me and I eat muesli!
My wife stayed with him and his wife a while back when we had the builders in. To watch him polish all that off was really something to behold.
