I have 3 constructive suggestions:
1) be sure that each family member (infants and the infirm excluded) have full snow gear (boots, hip lenght coats, hats that cover your ears, long undergarments, wool socks) so that if you do need to go out, you can.
2)once the weather gets more managable, get your weight in check and start a routine of walking, so if you need to walk 2-3 miles, you can do so without getting a heart attack
3) plan ahead. If the forcast says snow to hit by 6:00pm, try to be at your destination before the snow hits. Nothing is a rotten as getting stuck on the road in a blizzard.
With these small steps, you can manage (to some degree) until the snow is under control.
