Bumps

Being conscious, thinking beings, we sometimes find that nature’s priorities run a different course than our own. If life and death are the chips on the table, the consequences of these priorities take on grave proportions (pardon the pun).
Take for example hypothermia. This is a condition where the body’s temperature becomes abnormally low; as when ill dressed for harsh winter weather for example.
The body keeps a kind of emergency plan for various types of life threatening situations. For hypothermia, the plan is to conserve heat. One way to help achieve this end is to shut down the blood supply to non-essential body parts (saves on having to heat the blood). We are probably in agreement with the body about legs and arms as non-essentials. But the body’s “non-essential” list includes the head!!
