Oh yeah, trust me, concrete is -not- your friend when it comes to your lower body.  34 years on said material is why I now have an artificial right knee, and the left on is just coasting on Synvisk (r); when that stops working, then it goes bye bye as well. It justified my medical retirement from my store, as I can't do the jobs I used to do before all that fell apart. The best is barefoot over ground; you learn to =not= slam down on your heels, which keeps body weight+gravitational acceleration+ angular velocity from inflicting forces well in excess of 1,000 psi on your joints every time you step.

And on topic, I got a buncha Dusk stuff to play with. Unfortunately, it looks as if we are still in the Barbie and Ken mindset with regards to proper genitalia. On the plus side, I still have all the package enhancements rotica has had, so we'll be seeing about grafting Satanica's M3 gens onto this thingless thing.
