The first things to get cold are the extremities. They are the furthest distance from the central regulatory system. (Duh). Once they are cold - they start working less efficiently. More clumsy, less dexterity.
The hands are also arguably our most functional (and needed) body part. We use them for nearly everything. It’s the same way about business. Marketing, customer engagement and events are the hands of a business. They feel out the market. Their function is to provide feedback to the central hub by being the first line of offense and defense. Allowing the brain to make the best decisions possible.
Sometimes we need to take care of the core. Pull those hands to our chest and survive. Once we have thawed the blocks of ice - we emerge stronger, smarter and better.
