Filmmaker Karan Johar has said he feels he is born old and hence even directing second mature half of Kuch Kuch Hota Hai (K2H2) was easier for him.

Karan has been busy with the shooting of his upcoming movie Student of the Year (SOTY).

Recently he tweeted: "Am shooting the last day of the schedule in delhi....".

Karan seems immensely impressed with the three kids in the movie and has announced about releasing their exclusive images on Twitter, a social media platform, soon.

"the 3 kids in SOTY are lovely!!! Sid has a silent strong charm....Varun has a real fun bratty appeal...Alia is vivacious and super cute!!!" he posted on Twitter.

"For everyone asking SOTY is short for STUDENT OF THE YEAR...the film i am directing currently and will release in the fall of 2012!!!" he said.

While shooting for Student of the Year, Karan said he felt nostalgic by remembering his first directorial movie Kuch Kuch Hota Hai,

"At heart i think i was born old....even at 25 i felt more easy directing the second half of K2H2" Karan said.

He mentioned that since he will be turning 40 this year, working with the youth makes him feel all the more old and this might be his last youth film.

"Am going to be 40 in may!!! And filming with these 20+ actors has made me realise this is definitely my last stint at a "young" film!!!" Karan tweeted.
