Getting old

I have a problem: since I was born on 7.th of June 1947, I became and old man on the 8.th of June 2017 at 24:00 CET, it was sad but I managed to survive. Now I’m told that we are to become old at 75 instead of 65. What does it mean? I’ll remain an old man or the new regulations have a retro active effect so I’m young again to become an old man twice? I can’t sleep any more thinking about it.
