agreed! nothing wrong with body hair.
most contact sports should be restricted or modified if they are played by children/teenagers. the biggest offenders here would probably be american football and boxing, but this applies to any sport with a high risk of a head injury that is not purely accidental. and no, helmets aren't enough.
repeated head injuries often lead to lasting brain damage and neurodegenerative disease
(CTE) that negatively impacts the affected person's life and can be deadly years after the initial injuries.
if a person wishes to participate in these sports, they should have the age and the education to fully comprehend the risks and the consequences of their actions. children cannot, and their parents should not make that choice for them.
