If you want to be realistic and "real life", then abolish magic. There is no such thing in "real life", right? Show ma someone who can teleport himself halway across a continent and I'll give you my next month;s retirement check

Anyhow, I believe tat most people in real life can, for instance, at least master body building if the work at it. THe same goes for most secondary skills and even some of the combat skills . . just takes practice . . not that I'm any good at any of that stuff . . modern bomb disposal experts (GM Disarm Trap) are just plain people that have been specially trained for that type of work. Probably most people could do it if they were inclined and motivated enough to go through the training.
