SMART AS YOU WANNA BE

It’s incredible that in this day and age people will waste their money and even risk their health on questionable “brain boosters,” especially since there is no conclusive proof that they do indeed enhance brainpower (“Smart as You Wanna Be,” by Jeff Greenwald, Dec. 22).

My advice on how to effectively and safely increase intelligence is to do it the old-fashioned way, through hard work, studying and reading a wide range of books. Like any other worthwhile pursuit, there’s no shortcut to being smart.
