I remember when I was a little child I used to pick up grey hair for my parents. Time flies. Now my mum's hair is almost completely grey and she picked up grey hair for me. She said those who have hair like mine often have unlucky love life. She is still worried about me even I am almost 40. :-)
Believe it or not, there are so many grey hairs on my head. Easy to find them among my very black hair. My mum can recognize grey ones easily without wearing glasses.
