Don't have time to go into it now, but, for example:

> There is a wide variety of resistance mechanisms that hosts may evolve in response to their parasites. These can be functionally classified as _avoidance_ (lower probability of becoming infected), recovery (faster rate of clearance), tolerance (reduced death rate when infected), or acquired immunity. It is commonly thought that longer lived organisms should invest more in _costly resistance_.

> we define the optimal strategy as the level of avoidance that is both evolutionarily and convergence stable. We therefore expect longer lived hosts to evolve more avoidance, although this is not always the case. At low virulence (α= 1.75), resistance initially increases and then decreases marginally. Reducing virulence still further (α= 1.67), longer lived hosts may in fact evolve much less avoidance than shorter lived ones.
