Kool, I had to comment on this when I heard @humanearl talk about his wife for the first time. Yah, it sure is hectic that your wife now hits the gym, but I bet you it's for your own good, especially when she starts to burn some fat, and continue with that lovely shape she had when you first saw her.
And seriously, most wives need that exercise, especially for the much jobs they do in the house, helping to transform the house to a home.
My regards to her.
