Shouzou and Ine, an old married couple, are known to everyone as a pair of lovebirds. One day, they wake up to find they look like their younger selves! When Mino, their granddaughter, sees them, she's shocked by their transformation, and she's not alone!
And there's the fear of having 
a heart attack at the Sports Festival.
كما أنّه يوجد خوف من وقوع
.نوبات قلبيّة في المهرجان الرّياضيّ
Die meisten ham auch Angst
vor ’nem Herzinfarkt.
Y nadie quiere arriesgarse
a tener un infarto compitiendo.
Nadie quiere que le dé un infarto
durante las competiciones.
Seulement nous,
craignant un arrêt cardiaque.
C'è sempre il rischio che a qualcuno
venga un infarto durante il torneo.
E também tem o medo de acontecer
um infarto no meio da gincana.
На соревнованиях и сердце
может остановиться.
