OK, first, please don't laugh in this thread , and second, this thread is more towards adults and trainers who deal with the adult riders.
So... If you start serious riding as an adult (in late 20th-30th-40th) can you still learn a good riding (I'm talking about dressage and jumping disciplines) and compete successfully? All good riders I know started as kids. But not all of us had a luxury even to take lessons. And as you are getting older the muscles, bones and (sometime, but not for everyone) mentality is very different from those of child. So... Please, share!
