No less arresting is Lyme disease, which comes from the bite of a tiny deer tick. If undetected, it can lie dormant in the human body for years before erupting in a positive fiesta of maladies. This is a disease for the person who wants to experience it all. The symptoms include, but are not limited to, headaches, fatigue, fever, chills, shortness of breath, dizziness, shooting pains in the extremities, cardiac irregularities, facial paralysis, muscle spasms, severe mental impairment, loss of control of body functions, and—hardly surprising, really—chronic depression.
