You are the only one who can answer that.
You know your relatives more than us.
You know what's your situation more than us.
You know what's the best thing to do more than us.
And don't be too negative that some unfortunate will happen to you. Yes, I know you are just preparing for the worst-case scenario, but hey, you are just in the mid-20s, enjoy life.
Have you guys thought about such a scenario ?
Yes, but we do have different preferences.
