Playing football at an expert level requires specialized football  
knowledge, not physics. Playing lacrosse, similarly, requires expert  
knowledge of lacrosse. Similarly for violin playing, skill at  
bricklaying, etc. etc. Expertise, or what used to be called master- 
level skill, in just about any aspect of human activity requires  
expert knowledge **particular to that domain**, knowledge which takes  
approximately 20,000 hours - ten years of a 40-hour week - to acquire  
(pretty much independently of what area of expert skill one aspires  
to) and which does not transfer to any other area. The same seems to  
be true for the expert level of skill that we adults all have at using  
our own bodies for locomotion, speaking and social communication, and  
general adult competence at living in a society. These all also take  
around ten years of practice to acquire.    (02)
