The grey ones don't zap
In case anyone here is thinking to do the laser hair removal thing (which I highly recommend) do it before you get any grey hairs. The pigment(s) needed to suck up the laser ain't there. Same for some light colored hairs. Finally after 35 years of shaving my arms and back I splurged for the laser thing. My wife did it 'down under' and we loved it so much I went for it myself. Wife's 'down under' was $1400 and my back and arms were $2000. Most highly recommended.
If you don't think things could get worse; mess with me.
