Feature Requests: profile information - what is shared

There should be a way to hide personal data from being seen in the public profile. I really don't want to share my weight with my friends (or with people not my friends) I don't want to not have my weight in there as it's good for me to know (and is used in other calculations) but do we have to share that publicly? Items in the training summary that you want to share should be able to be selected by the user.
