Why is Chiranjeevi neglecting his health ?

Prajarajyam party president Chiranjeevi used to maintain his health and glamour when he was in movies but ever since he came into politics, he is seen putting on lot of weight.
He doesn’t seem to care for his personality anymore as he lost interest in acting in movies but this lack of interest on health is effecting him badly.
During the recent tours in flood effected areas, Chiru was seen struggling to bend and sit on ground to talk with people.
He was seen suffering from arthiritis, back pain and knee joint pains too.
People close to him say that Chiru is now more worried about his political career and doesn’t want to spend time on personal care , but on the other side, fans feel that Chiru should look in good shape and only then it’ll motivate him and his fans.
