Veteran actor Patrick Stewart says demise of his friends Alan Rickman and Leonard Nimoy have left him concerned about his own mortality.

The X-Men star says he is also worried about the well being of his wife Sunny Ozell, who is half of his age, reported Mirror.

"There is not a day goes by where I don't think of my mortality. I am 76 years old. I am married to a much younger woman and I cannot see her without reflecting on the differences in our ages and expectations and so forth.

"And this has been a horrible three or four years for my profession. My generation has been decimated. So many actors have gone," Stewart says
