Coming across a terrible dilemma | Brief letters

Brief letters: Ejaculation v sleep | Night-time stress | Brabazon legacy | Learning from mistakes | Pint or pony of porter

I was struck by two adjacent headlines: “More frequent ejaculations may boost men’s fertility” and “Extra 11 minutes’ sleep each night can reduce heart attack risk”. What a terrible dilemma.

• Given the impact of stress on the risk of heart attacks, I wonder how the worry about not sleeping for an extra 11 minutes is going to help me.

• Let’s hope that Brabazon isn’t an entirely appropriate name for the future new town (Letters, 24 March). The Bristol Type 167 Brabazon aeroplane was an utter commercial failure – aimed at a luxury market that no longer existed. After great expenditure of public money, only one prototype was built, and it was eventually scrapped.

• On the question of politicians and others in positions of authority learning from their mistakes (Letters, 19 March), I am reminded of Peter Cook’s character Sir Arthur Streeb‑Greebling, who, when asked whether he had learned from his, replied: “Certainly. I have learned from my mistakes and I am sure I could repeat them exactly.”

• It is rarely used now, but if you are ever offered a choice of a pint or a pony of porter over here, go for the pint (Letters, 23 March). A pony is a regular small wine glass or half a glass.
