A couple of days ago, I wrote a letter to my biological father. This is the second time I've sent this letter out, and I'm surprised i got a response back at all. His daughter texted me asking if we could talk. I was at work so I asked her if we could talk tomorrow and she said yes. I'm not sure how the conversation is going to go. If it goes well then I'd like to ask for his family medical history so I can treat my current health problems and know what I could be facing in the future. The problem is, I'm not sure what important questions I need to ask, so I came here to get some help.

What important questions should I ask from my paternal family?
