Bollywood film producer Karan Johar, who has recently celebrated his 38th birth anniversary on May 25, is feeling that he is turning old now.

However, the filmmaker is often termed as the "young filmmaker" as he debuted in the Hindi film industry at a young age.

He entered Bollywood with the SRK-Kajol starrer youth based film 'Kuch Kuch Hota Hai'.

On his social networking page, Johar said that he has started showing signs of maturating.

His latest post on the site stated that Karan has just got his first round of physiotherapy done; earlier there were just grey hair and now, there is a bad back.

Johar thinks that the label "young filmmaker" is not appropriate for him at this instant.

Even if Johar feels so, he would still remain in the hearts and minds of his fans as the talented director/ producer for his variety of movies like KKHH, K3G, Kal Ho Na Ho, Wake Up Sid, Dostana etc. (With Inputs from Agencies)
