Beginning with the featured Pro Football Hall of Fame game in early August, five weekends of exhibition games are currently played in the NFL. The start of the preseason is intrinsically tied to the last week of training camp.
Nits are head lice eggs, they are very small, about the size of a knot in thread, hard to see, and are often confused for dandruff or hair spray droplets. Nits are laid by the adult female at the base of the hair shaft nearest the scalp and are firmly attached to the hair shaft. They are oval and usually yellow to white. Nits take about one week to hatch. Eggs that are likely to hatch are usually located within Â¼ inch of the scalp.
Scientists have found that head lice either do not have a preference or prefer clean hair since they have an easier time laying their eggs and feeding in clean hair. What they also found is that head lice are more common in long hair. Interestingly enough, head lice infestations are also two to four times more common in girls that in boys â perhaps because of the long hair factor. Girls are also known to have more head-to-head-contact than boys.
