崔弘度，字摩诃衍，博陵安平人也。年十七，周大冢宰宇文护引为亲信。寻授都督，累转大都督。时护子中山公训为蒲州刺史，令弘度从焉。尝与训登楼，至上层，去地四五丈，俯临之，训曰：“可畏也。”弘度曰：“此何足畏！”欻然掷下，至地无损伤。训以其拳捷，大奇之。及尉迥作乱，以弘度为行军总管，从韦孝宽讨之。弘度妹先适迥子为妻，及破邺城，迥弯弓将射弘度，弘度脱兜鍪谓迥曰：“相识不？今日各图国事不得顾私以亲戚之情谨遏乱兵不许侵辱事势如此早为身计何所待也？”迥掷弓于地，骂大丞相极口而自杀。弘度顾其弟弘升曰：“汝可取迥头。”弘升遂斩之，进位上柱国。时行军总管例封国公，弘度不时杀迥，致纵恶言，由是降爵一等，为武乡郡公。开皇初，纳其妹为秦孝王妃。寻迁襄州总管。弘度素贵，御下严急，动行捶罚，吏人詟气，闻其声，莫不战栗。所在之处，令行禁止，盗贼屏迹。以行军总管出泉门道，隶于杨素。弘度与素，品同而年长，素每屈下之，一旦隶素，意甚不平，素言多不用。素亦优容之。上甚礼之，复以其弟弘升女为河南王妃。每诫其僚吏曰：“人当诚恕，无得欺诳。”皆曰：“诺。”后尝食鳖，侍者八九人，弘度一一问之曰：“鳖美乎？”人惧之，皆云：“鳖美。”弘度大骂曰：“佣奴何敢诳我？汝初未食鳖，安知其美？”俱杖八十。官属百工见之者，莫不流汗，无敢欺隐。然弘度理家如官，子弟斑白，动行捶楚，闺门整肃，为当时所称。未几，秦王妃以罪诛，河南王妃复被废黜。弘度忧恚，谢病于家，诸弟乃与之别居，弥不得志。炀帝即位，河南王为太子，帝将复立崔妃，遣中使就第宣旨。使者诣弘升家，弘度不之知也。使者返，帝曰：“弘度有何言？”使者曰：“弘度称有疾不起。”帝默然，其事竟寝。弘度忧愤，未几，卒。

    You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch（痒）,or just because it feels good.Boogers（鼻屎）form when dried liquid and cilia,the tiny hairs that line the nostrils（鼻孔）,trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.

    Otolaryngologist Erich P.Voigt, MD ,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.

    If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.

    Children, who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.

    So, next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.
