I wonder if this old ad from 1924 is really about a technique for breathing better or if there is something subliminal going on? Were women really looking back then to double their breathing capacity and gain ‘perfect breath control?’ Or were they seeking something else? Methinks things haven’t changed a lot in these past 80 something years.
Are these Psycho-Expanders (what a name!) still available? Anyone out there have one? I would love to see it.
