I wish I had been taught some tumbling tricks when I was a teenager and resilient. But it didn't happen. I find the best approach for me is to minimized crashes, especially the ones with likely bad outcomes. (I am near obsessive re: brakes, both having good stoppers but more important, predictable stoppers that will be forgiving in a panic grab. I have taken to "de-powering" dual pivots calipers with V-brake levers and still love the very predictable stopping of the old Mafac brakes.)
