I am a 35 year old man solo traveler. I have mostly planned a trip to greece, for October. My dad is 69, hobbling around with a cane, and won’t see a doctor because he is afraid of x-rays. My mother got mauled by a dog less than 2 years ago while walking in her neighborhood, and she slipped on ice and broke her arm, less than 3 years ago ... my great-grandfather with my same last name had a heart attack and died when he was 39, in 1934...
Should I worry about buying trip cancelation insurance? (What if my dad falls down the stairs in my parents home? Does it matter if it happens just before versus after I leave for my trip?)
