Do we get old because of telomeres?

In brief: No
The telomeres shorten with age and succesive cell divisions (and chromosomes replications).
They do not cause aging per se in us. Rather they shorten as we age. However, some people have inherited longer telomeres so they last longer before they grow too short to survive cell division.

Dr. Carlin is correct. The cells that take the worst beating as we age (brain cells) don't divide or shorten telomeres. Mice don't shorten telomeres but age like every other animal.
