Reader B wrote to Lifelines about his worries regarding his wife, a keen driver who is about to become an octogenarian:
My Japanese spouse of well over 50 years will celebrate her 80th birthday in a few months. Going to her local sports club for Ritmos dancing four times a week, she is as healthy as a fledgling octogenarian can be.
M also likes driving, and she does so like a 30-year-old. Over the years she has caused a couple of accidents, but managed to have her driver's license renewed every so often to this very day.
