Oh please Rob, I know it isn't 'Politically Correct', but could we please drop the 'Men vs Women' thing?

As I have opted to manage most of my RRSP's, I monitor my accounts, buy and sell stocks, etc. My wife goes to her 'investment advisor' (note the 'o' here) once a year and he tells her, "Oh this mutual fund hasn't done very well. You should sell it and buy this other one."

Some good friends, the wife was in banking, so he turned everything over to her and let her worry about it (he could probably do it himself, but, y'know).

Another friend gets all sorts of investment ideas from work. Even though he is close to retirement, he took out a mortgage and invested it in bank stocks reasoning the bank stock dividends were more than the interest on the mortgage (not sure how active his wife is in all this).

In short, I suspect you are trying to measure something that has a pretty 'wide' distribution and probably depends more on an individual's background than what washroom they use.
