What ails a boy who has his feet in a big bowl of warm watery Epson Salts?
When I was small it was a cup of hot Bovril and some bread. These days it's a fruity Yoghurt with a luxury foot spa.
So, what is he suffering from? Dropsy? The Vapours? In-growing toe nails?
No, after a long day running on the beach his sandals had rubbed sores onto his feet, and out came the healing Epsom Salts.
Do they work? No idea, but I suppose it can't do any harm. The Yoghurt works; that I do know!
