Skeletons in the Closet: When do bones turn to dust?

I know this isn’t really a “discussion forum” but I do have to ask:

When do “skeleton bones” turn to dust?

I mean is there anything that a conservative can overcome when it comes to stupid actions of their youth?

I just throw this out there. I am talking about things like DWIs, bankruptcy, etc. etc. Nothing like felonious.. but just maybe embarassing.
