Beachy head or anything other than a perfectly straight drop down to concrete is extremely risky if you ask me. I always think of attempts of the Empire State Building where people instead hit one of the buildings below or the videos of the people jumping off the hoover dam. Because it's a slope you see their body ricochet (as it would from a rock on a cliff face) and it violently breaks a limb(s) before they finally slide and hit the bottom. I'm also reminded of a 9/11 jumper than somehow survived the initial impact but mangled irreparably from the torso down, pleading to a first responder who put a black tag on her that's she wasn't dead. Or anytime there's water involved aka bridge/cliff I just think about how if you survive the initial impact you're now meters and meters underwater, bones shattered, in total shock and you die with every fibre of your being on fire as your lungs fight for oxygen to cling to life.
Point is to guarantee 'success' there's a lot more to consider than meets the eye. You might be lucky and hit your head on something first on the way down or your final moments could be a mix of sheer terror and agony.
Anyway happy thoughts happy thoughts
