我也顶着锅盖说一个吧。这个案子和那个拿枪打了妻子十四枪的案子不同的是，这是用拳头打的，如果不是一下打死的话，这个人的拳头也会很痛，但并没有停下来。说明这人已经在失控的状态下。至于为什么失控了，等警察拿出更多证据来。

Do you ever climb down instead of jumping?

I have a bad back and am afraid repeatedly jumping from high places will cause issues. Anyone else have a similar problem?

Almost always. it''''''''s explicitly stated etiquette to down-climb if possible in my gym.

You can usually traverse to an easier down-climb if necessary.

说不高的顶多是仗着自己个子高。

他这个landing动作也业余。

The Best Alternative to Jumping down from the Wall

As previously mentioned, repeatedly jumping down, even if using proper landing techniques, will eventually lead to joint damage. Tactics such as collapsing and rolling will absorb some of the force, but not all of it.

Down-climbing is the best alternative to jumping. If your problem is a difficult one and no down-climb route is provided, traverse over to an easier problem and work your way as far down as possible before jumping.

人的头骨是非常坚硬的。如果用手击打，手骨会比头骨先碎。所以男的手肿。这是要多大的憎恨才能徒手把头骨打碎致人死亡。

我相当认同楼主的观点，人生而不平等，连死都无法控制，天灾人祸谁也无法预测，谁都不知道下一个谁又是受害者。希望女受害者RIP。这个案件让我觉得女主实在太令人心痛了，和张莹颖一样让我心疼，但是也就只能同情，然后珍惜当下。
