Fifteen years older?! You think that woman looks 78? To me I'd put her in her mid-60s. She's 63. She looks like a 63 year old.

I think part of the problem of this talk is that it introduces the fact that older people/people with disabilities are judged on their appearances instead of their capabilities (which, with respect, you have just demonstrated). Then the talk sortof goes off into a "how to age gracefully" direction and abandons that original line of thinking (disclaimer, I only watched the first 30 minutes so far).

I definitely would be interested in addressing the first issue because, as they say, everyone becomes a old and/or disabled (unless like Tom Petty, you're dead).
