From Maggie Cobbett, Ripon, North Yorkshire, UK
I learned a lot from your article on static electricity, but not why my husband has always been more affected by it than me. For example, there used to be a department store called Schofields in Leeds, UK, that he avoided because touching the banisters on any of its staircases gave him a painful shock. I, on the other hand, never felt a thing(5 July, p 34).
