Although the exact focus occurs in a single point there is a range (in distance) in which there appears to be focus in your photo. This is the Depth of Field (DOF).
The DOF is affected mainly by apperture size and focal length (zoom). The bigger the aperture (lower f-number) and the longer the focal length (more zoom) the smaller the depth of field is.
So next time you are taking a portrait shot, max up the aperture and use a zoom lens (80mm+).
Of course, you can also use the portrait mode dial.gif if you have a newer SLR camera and it will do exactly the above for you.
