From his gospel, how do you know luke was interested in sickness and sick people?

I know Luke is interested in the sickness and sick people because he laid keen eye on the circumstances of how the lord healed the high priests servant right ear by touching it. He is also interested in noticing that how the touch of the lord is curing different sickness like fever of Peter’s wife’s mother, leprosy and a withered hand of a man.

(c) Luke noticed details regarding sickness.
