This is becoming (or rather, has been) an issue, especially as of late. Users (especially anons, at least one of which I've had to block) keep changing the height and weight without providing a source, and it is usually reverted with the next user asking for a source.
However, source or not, most articles don't have sources for the heights OR the weights (or even the age, for that matter). Perhaps those fields ought to be removed. I'm searching for sources and I'm not coming up with anything except for links back to here.
What say you?
