25、宵追剧打麻将的姐妹吗？怎么一声不吭全变了！凌晨两点的兴奋极品且自摸三家“头天熬了夜，第二天走路打偏偏。”朋友大西“以前通宵都没事，现在起码要缓一周才行。”朋友小刘“熬夜玩儿还好，如果是工作熬夜会很难受。”所长“11点眼皮打架，十二点手机砸脸。”朋友老陈“熬了夜眼袋半个汤圆大，人不清醒真的遭不住。”朋友大汤圆这些昔日的熬夜选手如今由于心态或身体的原因，纷纷变成了退役熬夜员。到了一定年龄，年轻人对熬夜开始心生畏惧，不是怕老，是真的怕死。就像是你几年前亲手埋的一颗炸弹，料不到它哪一刻会炸，你开始紧张身体的每一次异常反应。“心脏不受控制突突跳的那段时间，我以为死亡的钟声要敲响了。”“有一天在地铁站突然
