The Stormlight that Dalinar now has access to would help to keep his body in good health, so that could survive forcing longer than his father's. Also, just because his father had a weakness in his mind in his later years, that doesn't mean that Dalinar will inherently. Keep an eye out, folks. I think Dalinar will be leading the Radiants for a very long time.
Now Lift. Lift is an amazing person. I like that she has her goals and doesn't let anyone, let alone the thing bonded to her very soul, get in the way. That is a good attribute to have, especially for someone with compassion like hers. It makes her more likely to be the kind of person who will protect like Kaladin wants to with all the healing power of an Edgedancer. All in all, I like Lift. My favourite character in all of the Cosmere is still Kaladin. And maybe Dalinar.
