Yeah the best way to fall is to keep your palm outstretched but in-line with your wrist and forearm then try to let your hand and forearm take the brunt. If you do it properly the shock will be spread across your forearm minimising pressure in any one specific place which will help prevent breaks. If you feel yourself going down head first, do the same but place your forearm bone across the middle of the top of your skull and tuck your chin. Again, try to land on your arm, if you do it properly, you’ll end up doing a forward roll and you should receive no injuries at all. I learned the latter one years and years ago then fell in my garden recently while stepping over some branches. I didn’t realise how much of a reflex it was until I landed back on my feet wondering what just happened.
