Talk about thread hi-jack
I read somewhere you are actually taller in the mornings than you are at night. Its due to the fact your spine can get compressed during the day (mostly upright) and will uncompress at night during sleep.
Of course as you get older, the spine will eventually compress over time and stay that way. So Mark, measure yourself after a long night's sleep and you could possibly hit 5'9
Anyone remember the Seinfeld episode when George didnt want to take off his elevator shoes since they made him 2 inches taller...hilarious!
