Can vouch for 5TP physics....About 6'4" and two fitty, though I think the last time I saw him this past June he mentioned being at about 240.
Put it this way....The SheBar is infatuated with both his looks and his personality and she's got pretty stiff standards (go figure how she ever settled with me).
If Mrs 5TP and I are ever in a shared plane crash, he can expect SheBar to be delivering him some sympathy casseroles.
Hopefully, he'll have had at least one successful dump by the time that fateful day arrives.
