Sure, a life coach can do you good. But sometimes what you really need is a life referee.

Yours would nail that thunder-stealing colleague for unsportsmanlike behavior. He’d give that date who never rang back a time out. And on those feet of yours? He’d call unnecessary roughness.

Obediently, you’d march over to G Spa, where a truly lightning-fast solution to your nasty little problem awaits.

It’s The Machine, a new buffing, spinning contraption imported from South America that looks like a cross between a blow dryer and an industrial sander. A worthy add-on to a pedicure, it removes even the most stubborn calluses with a quick, giggle-inducing pass.

Afterward, light on your feet, you’d bounce down Newbury Street.

All the while, delighting in a) your baby-soft heels and b) the fact that someone, for once, is finally on your side.

G Spa, 35 Newbury Street, Back Bay (617-267-4772 or gspa.biz).
