I hope the tiles didn't de(feet) (heh) you too badly. We have a bunch of spare tiles in the garage, and those boxes are the best - they're full of heavy, fragile stuff, the carboard is fickle, and they're often stored in environments were the glue holding the box together is likely to fail due to the ingress of heat or humidity.

A perfect exercise in anxiety and risk management.

I too, will be ageing at some point (probably sooner and faster than I'd like) - I am curious, do you have any resources you used when starting out with kettlebell exercises?

I'd love to benefit from your research as opposed to doing my own :P
