This is the first time I get credited in an article for... writing a plotting script. Thanks to the main authors !

We also had very interesting scientific discussions along the way, but that might come in an follow-up one day :)

🚨 Late preprint alert!
Why do biological process rates scale nonlinearly with temperature, deviating from the straight line on an Arrhenius plot? The key may lie in their inherent complexity!

En résumé:

-Il s'agit d'un décalage de calendrier de la réforme.
- 3,5 millions de personnes gagnent 3 mois (âge et durée)
-Cela ne change rien pour les autres:
- L'âge de la retraite atteindrait 64 ans en 2033 au lieu de 2032
-La durée de cotisation atteindrait 43 annuités en 2029 au lieu de 2028.
