London, November 19 (ANI): US President Barack Obama has new concerns to address in addition to the stock of national and international problems - greying hair.

The 48-year-old leader confessed in a one of several interviews before heading for Seoul, that he had shed pounds and was left with more grey hair during his first year in the White House.

My weight fluctuates by 30 pounds - it has for years, the Telegraph quoted him as telling NBC television.

I'm still wearing some of the same stuff I did when I got married 17 years ago.

My hair's gotten a lot greyer, there's no doubt about that, but I'm not sure that's (not) just because I was about the age where my hair was going to start getting grey. (ANI)
