最近读了一篇博文，说是一个从内蒙古山区于第一届高考就考上大学，后来又到北美，并成功成为房地产大地主的男性，却意外地在一次旅游度假时在大浪中玩水时溺水身亡。更有甚者，他和妻子一起玩。而且妻子水性很好，曾经是校游泳队的！ 可是根本就毫无查觉，知道离岸时才发觉不对劲！（想想：这妻子也太忘乎所以了，或者就不懂溺水特点和防范措施！）
这让我想到我原来读关于溺水的一个记忆。那就是，
多数人是不会喊叫救命，甚至不会做出任何求救的动作的！
因为很难！
见下面一段溺水时人的一般的本能反应：
Instinctive Drowning Response:
- In the vast majority of cases, drowning people are physiologically incapable of calling out for help because the human body is wired to give priority to the primary respiratory function, breathing, and not to speech, which is a secondary overlaid function.
- Drowning people's mouths are not above the water long enough to enable them to exhale, draw breath and call out, they have barely time to exhale and inhale quickly before their mouths go back under the water.
- When we are drowning, our natural instinct is to press our arms outwards and downwards onto the surface of the water so we can leverage our bodies upwards to catch our breath.
- Waving arms about to draw attention is a voluntary movement: we have to stop drowning first before we can physically perform voluntary movements like waving for help, grabbing rescue equipment or moving toward a rescuer.
- While in the Drowning Response, people stay upright but they don't perform supporting kicks, and unless rescued, they struggle on the surface of the water up to 60 seconds before they go under.
那问题就来了：如何及时发现溺水？ 我能想到的：
1. 同伴：跟同伴一起，互相照应。清楚地讲明，溺水通常是无声无息的！
2. 没有救生员的地方不下水！
想想，如果那个妻子深知溺水的知识并保持高度警惕，就不会有这个悲剧！
想到这也是健康的一个话题，发到这里与大家共勉！
PS：能不能开一项溺水呼救训练课呢？少数人还是能够呼叫的。那么为何不能通过学习与训练掌握这个技能呢？就像我们通过学习训练掌握微积分一样！
