The decision of whether to hide the fact or submit oneself to the scrutiny of the scientific community would likely depend on various factors, including personal preferences, individual circumstances, and the potential implications of such a discovery.
Some individuals might choose to keep the information private due to personal reasons or concerns about privacy and maintaining a normal life. They may prefer to live their lives without the added attention or potential disruptions that could come from revealing such a unique circumstance.
On the other hand, there could be individuals who would be fascinated by the scientific implications and choose to share their condition with the scientific community. They might believe that their situation could contribute to medical or scientific advancements and willingly subject themselves to scrutiny, research, and potential investigations.
It's worth noting that if someone were to stop aging or exhibit an extraordinary biological trait, it would indeed generate significant interest from scientists and researchers. However, the decision ultimately rests with the individual and their comfort level with attention, potential study, and the impact it may have on their personal lives.
