ribka... I agree with your remarks 100%. Like you I have no illusions about being able to fight as I could when I was younger, but I have learned to keep certain realities in mind and have changed my training/preparedness accordingly.
The big takeaway from that article in my opinion was the grappling statistics... I'm not saying there's no place for strike techniques in one's personal training, but it's a low priority for me and has been for some time.
Most on here have no experience/training in DT, but I know there's enough interested parties to make it worth sharing.
