Re: [jski123] Can't jump anymore, what next?
Try tec diving (especially deep air, "BASE" side of it), or cave diving if you want a full-on trip. If you get a bit of help with your gear on the ground, your back & neck will be fine in the water. This activity has all the dangers and built-in drugs you can handle (and then some), and if you do it right you'll be shitting your pants for hours instead of mere seconds
Paragliding & speedflying might or might not be a substitute for BASE (didn't work for me), however statistically they won't be any safer or better for your spine.
Yoga etc is a great path. Just beware that it's more of a spiral than a straight line and it might bring you right back to the exit some day - feeling much better, at least!
After stopping a couple of times for 2 & 3 years (no injuries, just loosing interest for a while), i've found that nothing could replace BASE as such. However, BASE itself has evolved so much that what i do now (wingsuits in the mountains) has very little in common with slider-down urban rage of 25 years ago.
