Why shouldn't the pension age for women be raised?

I think this is because, while men's retirement age has been 65 for a while, women's retirement age has gone from 60 to 65 as of last year. The issue, I think, is that, regardless of men and women being the case, if the age is increased by so much now, then in the future it will probably continue to increase. Also, back to your actual question, I guess it's because women have a harder time in their older age, so will probably struggle more than the average working man of the same age.
