I suppose that diversification is in my future. I've been sticking to cardio because my goal is mostly blood-pressure control. Fortunately, I'm a pretty squarely built guy who doesn't pack on weight easily. But mixing it up would be a good idea.

As for cons . . . I love getting out of the office (read: away from home) occasionally. I just wish I could do it as some super-important bigwig who flies business class to sip coffee and tug on his beard. Getting up early, sacking out late, lugging crates, and flying crazy hours really sucks energy. Still, I'd rather do that than stay parked at home 24/7/365.
