It's a weird question and related to Jankovic, Ivanovic and to a lesser degree Djokovic. These young pups are all darker complected than their parents, signifcantly so in Jankovic and Ivanovic's case. Haven seen all their parents in this wimbledon, I'm curious if they like sun tanning in Serbia or something, cause I don't think exposure on the tennis court can quite explain Ivanovic and Jankovic. Djokovic is more explainable since the difference is really pretty slight(but still noticable).
its healthy to have a tan
I think serbs tan very easy.. ill be out in the sun for a good few hours and get a nice tan
