Good for Gianluca Grimalda (Refusing to fly has lost me my job as a climate researcher. It’s a price worth paying, 12 October). So many people, myself included, would have taken the easy flight out and sacrificed their principles regarding climate change and the impact of long-haul flights. Hopefully his employers will have a rethink. Judith A Daniels Great Yarmouth, Norfolk In a newspaper that regularly features people struggling to pay for life’s basics, I was surprised to read Sali Hughes extolling the virtues of an anti-aging cream at £75 (At last, gentler anti-ageing serums that really work, 13 October). I am almost 80; let me think, do I buy a week’s groceries and put a bit towards bills, or fork out for this? Jean Austin Crawley, West Sussex Derek Niemann (Country diary, 12 October) considers that women don’t feel safe walking in the countryside. I must reassure him that this woman has rambled alone all her life, and has never felt unsafe. On the other hand, I have been physically assaulted three times, and verbally many times, when walking in towns in daylight. Jenny Haxell Ipswich, Suffolk So, Madonna’s concert features “a witty recreation of a drag ball for Vogue. She performs Hung Up in the midst of writhing topless female dancers” (Madonna review – queen of pop dazzles with her greatest hits, 15 October). Sadly, in this day and age, writhing topless female dancers are still anything but funny. Debbie Cameron Formby, Merseyside I’ve been rescued by HRT for nigh-on 40 years, after an early menopause (Letters, 13 October). I’m still caring for a 92-year-old husband, and dancing the polka, and don’t intend to stop. Elaine Fullard Oxford Have an opinion on anything you’ve read in the Guardian today?
