Sir, – Further to Lucy Kellaway's article ("Having a tattoo of your employer's logo is just creepy", May 19th), before having tattoos applied, the modern executive might be mindful of the tried and tested and scientifically proven epidermal pigmentation cerebral (EPC) constant, which states that the area of body skin covered by tattoos is inversely proportional to the grey matter. – Yours, etc,
