Interesting....what time of the day did you measure yourself? you know that people are about an inch taller in the morning when you just get out of bed compared with the evening
well i measured both times late at night...
on that note i was considering this stuff about jumping off things for a while before going in...at first it makes some kinda sense. Compress the tissue between your vertebrae to make yourself shorter. But then I got to thinking, they will prolly then swell to make it harder to squeeze yourself down those fractions of and inch.
Seems we would be better off just practicing using muscles to compress the lower back and neck and slouching without being noticeable.
