Answer:

I think that cutting P.E. is not good. The class allows us to combat our growing obesity problem and it provides leisure time for students, something they sorely need. In Finland, schools have 15 minute breaks after every 45 minutes of teaching. This keeps the kids relaxed and happy. Sadness and stress are damaging to their health and their grades.

Explanation:

At a time when American children are increasingly absorbed in their screens and one-third are overweight, the need for robust physical education is acute. Last month, the federal government updated its recommendations for physical activity for the first time in 10 years. The guidelines now include recommendations for children as young as age 3, and advise a minimum of 60 minutes per day of moderate to vigorous activity for ages 6-17.  Alas, only one in five teenagers meets this standard.

Inactivity has been called “the new smoking,” and the prevalence of obesity and inactivity may well mean children today will lead shorter lifespans than their parents. Children desperately need to learn the importance of physical fitness, how to achieve it, and how to maintain it. Well-taught physical education keeps students moving and motivated, building their competence and confidence so that they can stay fit over a lifetime.

How can a woman give birth to a child and avoid transmitting herpes?
netineya [11]

Since herpes is spread from active skin infection and not from latent infection, a newborn baby can be infected with herpes only if they are born while the virus is active. Neonatal herpes generally occurs if the baby's skin becomes infected during the birth process.
