Over at Science Daily, they've been talking about a group of nomadic cattle farmers in Africa called the Masai. What's so interesting about them? They eat a diet high in fats, and yet their rates of cardiovascular disease are way down, they have low average body weights and their blood lipid profiles are generally healthy. What's their secret? Walking.

We're not talking about mega-fast speed walking here -- just some low-level strolling ... and lots of it. In fact, the Masai are believed to walk about 20 km a day -- that's about 12.5 km.

OK, so walking that much every day isn't an option for many of us, but getting in our 10,000 steps a day and eating a balanced meal are things we can -- and should -- do to keep our chances of cardiovascular disease down.
