囧發現:長黑痣讓你更年輕健康

Men and women with More moles are less likely to develop osteoporosis and look up to seven years younger than their true age, according to researchers from King's College London. Other suspected benefits include tauter muscles and healthier eyes and heart, which outweigh the risk of skin cancer linked to the presence of moles.

倫敦國王學院的研究人員近日稱，黑痣越多的人越不易得骨質疏鬆症，且比真實年齡看起來年輕7歲。研究人員還稱，黑痣帶來的好處可能還有緊繃的肌肉、良好的視力以及健康的心臟，與這些優點相比，“黑痣可能與皮膚癌相關”的說法似乎不足一提。

Researchers looked at 1,200 non-identical female twins aged between 18 and 79 and found that those with more than 100 moles were half as likely to develop osteoporosis as those with fewer than 25.

研究人員調查了1200對年齡爲18到79歲的異卵女性雙胞胎，結果發現，相比身上少於25顆黑痣者，長有100多顆黑痣者患骨質疏鬆症的概率更低。

People with lots of moles are known to produce white blood cells with unusually long telomeres, a part of DNA which allows it to replicate, preventing deterioration. The longer it is, the more time before it starts to degrade.

原來，長有較多黑痣者體內的白細胞端粒（在染色體端位上的着絲點）更長，而端粒能夠使得脫氧核糖核酸不斷複製，以防老化。端粒越長，老化速度越慢。They believe these findings could pave the way for a cream which "switches off" wrinkles, doing away with the perceived need for collagen injections or plastic surgery.

研究人員認爲這些新發現可爲“去皺霜”的研製開闢新道路，同時打消人們注射膠原蛋白、做整形手術的念頭。

Moles are the result of rapidly dividing cells which produce a dark pigment in the skin, usually in childhood. They often begin to disappear from middle age but in some people they continue to spread.

據瞭解，黑痣是可分泌暗沉色素的某種皮膚細胞快速分裂的結果，常見於人類幼年階段。黑痣往往消失於中年時期，但也可能持續擴散。
