McCain's age

What makes McCain stand out like a sore thumb is his age in comparison to other candidates. He is 72 years old, while Hillary Clinton is 60 and Barack Obama at 46. Several fear that he will only serve one term as president therefore it is essential to have a grand vice president with him at hand. Others believe that McCain might even die during his time serving as president. But in the video down below he states that his age is not an issue for the fact his mother still lives. I think that this may affect him emotionally and can cause him to lose some votes. He would be the oldest president yet. I personally find no flaw with his age. I believe perhaps he would put in the best effort because of his shortage of age.
