Hello, TAN!! Oh, wait... Still not doing any running, biking, or especially swimming for the past 8 years due to hip issues, BUT, a past BT'er (who I've kept in touch with) has provided some positive feedback and encouraged me to get checked out after their successful hip replacement. My oldest son is a fitness guy doing a lot of body-building/weightlifting, my 2nd son is in a tri-club in college and bikes a lot (completed a 200+ bicycle ride across Wisconsin on the first weekend this month (Aug) in just under 14 or 15 hours) , and my youngest son is one helluva swimmer in H.S. and club swim and getting some early recruitment looks. For now, I just like good craft or import beer.
