晚饭吃多了有点儿撑得慌:液压泵,心脏,剧烈的体育运动

首先俺坚决认为人的寿命天注定,医学的进步和健康的生活方式让人均寿命延长而已,
Wingreen 说起心脏和液压泵类似,俺想了想很有道理:
1. 液压系统是现代机械的宠儿,高效安全高质。它和人体的血液循环系统一样遵守流体力学原理。
2. 不同类型的液压泵从出厂时就有有不同的使用寿命,两三年,十年都有,和人的心脏一样有好有一般。有的心脏可以跳几亿次,有的可以跳十几亿次。
3. 影响泵正常运行的最重要因素是保持液压油的清洁,就像血液中胆固醇和其他杂质会影响心脏运行一样,而你的肝肾之类负责排毒的器官功能和遗传有关和体育锻炼无关。健康的饮食远比锻炼更有效。
4. 液压泵最怕冲击载荷,造成系统压力紊乱会损坏内部元件,就像人的心脏一样,剧烈的运动有百害而无一利。
那我们为啥要锻炼呢?
1. 适当锻炼可以让心脏跳动更有力,让心率正常或更低一些,出汗可以让排毒更快更顺利。
2.体育运动带给我们身心愉悦,反应敏捷,更加灵活高质量地享受我们的宝贵的每一天。
所以俺以为:快走,慢跑,骑车,游泳是最好的方式。
至于要练块头有阳刚之气,泡妞之类,霞飞就是个最好的例子,没啥肌肉照泡不误,因为女人不看重这些。
司空老弟说的史泰龙和施瓦辛格还是算了吧,刚过70, 口眼歪斜,看着血管随时都要爆裂的样子。
说了半天,关键还是俺没钱,要不早就办健身membership去了。
