Why Pre Existing Conditions Matter So Much

Senior travel insurance often comes down to how medical history is handled rather than anything else in the policy wording. While going through https://www.globelink.eu/senio....rs-travel-insurance. I noticed the page says more than 50 pre-existing conditions are covered free on standard policies, which is the kind of detail many people search for first. How early do you usually check the medical-condition side before deciding a policy is worth considering?
