Veteran actress and social activist Shabana Azmi and her husband poet-lyricist Javed Akhtar have urged people to sign up for organ donation.

Shabana took to micro-blogging website Twitter on World Organ Donation Day on August 13 to share that she and her husband have already signed up for the same.

"Sign up today as an organ donor on http://www.organdonationday.in both @Javedakhtarjadu and I have donated ours," Shabana tweeted on Thursday.
