The top 5 has been strong. It has stayed the same since Randon's death (17 January).
Maria was always a strong SC with good potential and indeed she surpassed all 116ers from South / Mediterranean Europe (Jeanne Bot, Maria Giuseppa Robucci, Ana Maria Vela Rubio, Giuseppina Projetto). She has good care, her family is active in social media, and she remains in good condition despite some decline so 117 is possible but we know that it is a very exceptional age, very difficult to reach. I think if she reaches 117 she also has many chances to reach 117.5 because summer is less dangerous for SCs
Fusa Tatsumi has been in very frail condition since at least 3.5 years ago but she remains stable like we have seen with other Japanese female SCs. She always gave me off the vibes of Tajima as a case and she is indeed becoming a new Nabi Tajima.
I don't think Eddie Ceccareli's dementia is immediately necessarily dangerous for her. Obviously it's a negative aspect like her physical decline which is not a good sign but still she is quite strong physically for her age.
Tomiko Itooka was in miraculous condition as an old woman, as a centenarian and as an early supercentenarian. It is a shame to see that she has somewhat declined but she is still strong and surely much stronger than many other Japanese SCs... She also has a wealthy background and good care.
Inah is another former very strong case with some decline due to advancing age. It would be interesting to see her getting far, given that another nun made it at the top 4 of the oldest people ..
