About snow tires

So I've successfully driven back out to the countryside last night, despite bad snow squalls and white-out conditions on several of the roads along the way; it took me an extra hour to get up there than it usually would b/c of this, with several rumblings of the roadsides when I swerved over the sides....
Which brings me to the snow tire issue; I know a few people have suggested that I get some for safety's sake. However, I did manage to get by 2.5 winters in Ottawa without them. Also, I'm looking at it from the perspective of probability; I get the feeling that my car, in general, being forced into going head-to-head with a truck/side rail/SUV/compact sedan/mini van, will likely lose. I thus suspect that if I was in a serious enough accident, I would probably die. Which, honestly, I think is better than being left quadriplegic. Which, after having seen many patients (today included) who have been left in various severe levels of disability d/t motor vehicle crashes, is not really my inclination. I figure, if I get snow tires, it just increases the chances that I would survive a crash. Not my inclination. "It's better to burn out than to fade away" states Tom Petty. I'd be inclined to agree; I think I'd rather smash up spectacularly than be partially crumpled.
On another note: I'm staying at this lovely little farm house B&B, so I just thought I would put a little advertising plug in for them: http://www.cedarbraeinn.ca/ . The hosts are lovely people, and it's a beautiful piece of property (though, admittedly, it's under a heck of a lot of snow right now, so I dunno what it looks like when it's all not snowy). It's nice to look out the window and just see trees and snow-covered fields out to the horizon....
