There is nothing for you to worry about at the moment, PIP the proposed replacement for DLA is not law yet and even if passed, will not come into affect for several years.
You say you are currently 62, and our information is that that the changes will probably not apply to the over 65s, which you may well be by the time implementation begins.
Even if they do apply, there really is no reason to assume you would not qualify.
