I'm not this person's Facebook friend, and thus could not post a comment on that wall, so I thought I would put my thoughts here instead.
"I disagree, in the sense that this statement is only true if you take the position that external forces (other people, the weather, diseases, accidents, etc.) and internal forces over which you have little or no control (age, genes, illness [mental and/or physical], etc.) have no effect on the decision making process. No one makes choices in a vacuum.
On a lighter note, I find it kind of amusing that there is no period after "Period". I wonder who made that choice… and why?" -- PL
