Identify your goal or target. For example, if you want to run 30 miles in a week, 30 miles would be your goal. Alternatively, if you want to raise $1,000, $1,000 would be your goal. Measure your progress toward your goal.
Head lice infect hair on the head. Tiny eggs on the hair look like flakes of dandruff. However, instead of flaking off the scalp, they stay in place. Head lice can live up to 30 days on a human. Their eggs can live for more than 2 weeks.
Because head lice have no built-in ability to perform long-range reconnaissance they can not scout out new heads to infest. They are creatures of opportunity and simply move from head to head when those heads (or infested hair) come into contact with each other.
