Taking the skateboard and going out to roll is something pleasant;
As long as you have control on the board at a basic level that is necessary to avoid stones, climb sidewalks, lower them, react quickly in case of losing control to avoid falling.
All the hours of skateboarding at a young age are giving me many days of infinite fun, knowing more about the connections of the musculoskeletal system.
My recommendation to people from 30 to 40 who want to start learning, is to find an already experienced friend, thus giving them a basic routine to be able to flow and avoid many falls.
