I remember as a medical student in the early 1980s hearing the late, great epidemiologist Sir Richard Doll talk about the importance of aspirin in reducing fatal heart attacks (Daily aspirin unlikely to help healthy people to live longer, 17 September). Sir Richard was well aware of the risks of internal bleeding. The solution he suggested was dosage – only a tiny amount of aspirin is needed to protect the heart. When we pressed him for a definitive dose, he replied that he kept an aspirin in the bathroom and licked it every day.
• The answer seems obvious to me (Discounted admission tickets for over-60s in UK ‘unfair to young’, 17 September). Keep the discounts on weekdays for the people who have the time and money to visit museums and galleries. On weekends swap the discount to families.

• Why do you describe the growth in the use of e-bikes as a “craze” (Report, 15 September)? It’s the most positive thing to happen in urban transport in years. E-bikes are popular for good reason because they can replace most car journeys in town. At last there is hope that their use will bring about an end to the carnage on our roads caused by the misguided craze for driving.
• Re possible post-Brexit copyright issues concerning health warnings on cigarette packets (13 September), and in the spirit of blue passports, perhaps British artists could be commissioned to replace them – David Hockney, for instance, immediately comes to mind.
