Every time, I die like an idiot because of a risky jump, because I slip on a stone or because I fall into a hidden hole. And then, it's a real pain to go back all the way from the respawn point to your last location.
Fortunately, it won't happen again if you own the brand new jetpack device. Yes, you read well, a jetpack, folks! You will no longer fall in caves and crash your skull head first on a sharp rock. The use is child's play: once you are in the air (jumping or falling), simply hit and held the jump button to trigger the jetpack til you want to land.
Beware though of your fuel gauge! Even if the gauge fills itself when the jetpack is not used, the fuel tank has a short capacity. And you will have to manage it well if you don't want to run out of gas at 50 feets high. Now, time to go back in the sky. Woosh!
