As a rule, we don't change much even if we get power. We just get more license to do what we already do in some shape or form.
Thus if you had telekinesis would you become totally out of shape due to using TK constantly? Chances are yeah if your already lazy LOL.
Let's just pretend that people won't care one bit about you and your powers and won't even film you even though you have powers. They treat all you do as normal, even though your not.
