If you found your age reversing how much would you worry about it?

Say you were on vacation and you found some strange ornate coin, medallion, etc. You bring it home as a souvenir. After a month or two you noticed you are getting younger, not very fast but quick enough for you to tell. If you had wrinkles they were fading, hair coming back to bald or thin spots, if you just started shaving, you found your beard not growing back, or your junk didn’t pop anymore, or your period stopped, etc. Would you worry about how severe the age reversal would be, when or if it would stop? Would you worry about becoming an infant again? What if you could not find the coin/medallion, would you figure that was the key? Would you go to your physician to be tested, or see if science or medicine could stop the backward slide?
