According to Wikipedia the Chernobyl explosion happened April 26 1986 , so that was 22 years ago.
Consider what this e mail says,
" He is actually 21 years old and attended pioneer school in Kiev . His
name is Sasha and he is a great example. "
"He was four years old when the Chernobyl disaster happened - he stopped
growing that year. "
Somebody has not bothered to do any maths...but lets not forget that this is an unofficial e mail, the kind that the WT itself criticises.. One only has to look at Snopes to see how the human mind loves to believe something unusual..
