That might sound a silly question, but today on You and Yours they were talking about the changes in employment and retirement ages. Some sort of actuarial expert was interviewed, who claimed that "Today's 70-year-olds are as healthy as 60-year-olds were ten years ago". (She took this as proof that people could easily go on working past 70.)
Hang on, I thought .... that's the same people! Ten years ago, today's 70-year-olds were 60. I'm not far off 70 myself. Does this mean that all my age cohort are just as healthy as we were ten years ago? Have we stopped ageing, then? Will the 80-year-olds of 2027 be as fit as today's 70-year-olds?
I'm sorry but this is rubbish. I am very healthy and fit for my age, but I am slower, both mentally and physically, than I was ten years ago. I need to rest more often. I have some arthritis that causes me pain. My hearing and eyesight are definitely worse, and I take longer to process new or complicated information. I am, in short, a perfectly normal 69-year-old.
Other people born around the same time have aged similarly. Some have already died while still in their 60s, so they certainly aren't as fit as in 2007! Others I know have had strokes, chronic chest problems, hip replacements or cancer in the last decade; they are still living worthwhile lives, but would be less fit for demanding employment now.
Age isn't just a number, and we can't mark time and avoid getting older. It makes me very cross to hear people glibly tell us otherwise.
