do you like skateboarding? it can be a job, method of movement or recreational activity
I've tried it once, but I was not very good.  I do understand that there are some that make really good money at it though.
yes, it is truly an action sport, performing tricks can be very tough
Do you know any people that make really good money at it, besides Tony Hawk?
Andrew Reynolds is a profressional skateboarder, he is pretty good
I wonder if they ever get injured while doing their tricks?
certainly, many do not even wear helmets, which does not help
Oh my goodness!  They should wear helmets to protect themselves.  Do you have any statistics on kids without helmets?
Helmet
A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g. UK policeman's helmet) without protective function are sometimes worn. Soldiers wear helmets, often made from lightweight plastic materials.
The word "helmet" is diminutive from "helm", a medieval word for protective combat headgear. The medieval great helm covers the whole head and often is accompanied with camail protecting throat and neck as well
Skateboarding
Skateboarding is an action sport which involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding will be represented at the 2020 Summer Olympics in Tokyo.
