So Cold.

On days like today, where it's quite probable that hell has indeed frozen over, I am grateful for modern conveniences such as indoor heat, achieved without a zombie attracting fire. Though this does raise the question of whether or not zombies are able to sense heat.

Afterall, snakes can sense heat, as a means to locate prey, might zombies not also be able to sense heat? We as people can seek out heat for survival, but most of us are not sensitive enough to be able to locate heat-giving sources such as warm-blooded creatures. Because of this, I believe that zombies would not use this as a primary, or even secondary, means to locate prey. Still heat is best used in a contained fashion. If you have means to use heat discreetly, such as in an urban area where heat is used everywhere (at least immediately after the necropalypse) you should be able to stay warm safely.

However, I can't stress enough how bad of an idea it is to use fire. Zombies have no natural aversion to fire, but the crackling and wavering light will most likely attract their attention. And one of the few things worse than an attacking zombie is an attacking zombie that happens to be on fire.

So now, in this plausibly zombie-free time, it is a good time to obtain to some long underwear and heat-retaining clothing and practice wearing it. Yes, I know it sounds silly to "practice" wearing clothes, but it is important to understand and be prepared for the level of mobility that said clothing will provide. Though there is one positive to wearing bulky clothing: it's a lot harder to bite through.
