I think the answer is the pituitary.
Yes. It protects against 90% of cervical cancer in women, protects against 90% of genital warts in men and women, and protect against cancer in the genital area when you are older. Signs of HPV are genital warts and itching, but do not always show symptoms. It should be mandatory in my opinion because sexual partners are not always honest, and if a simple shot can prevent life threatening cancer it should be a necessity.
I would say swimming but imo karate requires more kicking with complex and diverse skills
The reson you should know this is because it isnt all about weight. What if the person weighs 200 pounds.......it might not all be body fat a lot of it could e muscle
