Just make an effort to clear your walk. A shovel-width path, a bunch of salt, anything. I really can't understand the 2 or 3 homeowners near us, younger and seemingly healthy people, who don't appear to even try.
If you've got a big loud snowblower (I do) and you crank it up early in the morning (sometimes I do), hit a few of your neighbor's walks too (I do). Where to draw the line is up to you.
Note- the folks mentioned above are that near me, otherwise I'd help em out sometimes.
