This endpoint follows the provided rules and examples:

- Uses `@router.get` decorator for the GET method
- Checks the request method and raises 405 error if not GET
- Filters the `people` list to include only those over 50 years old
- Returns a response with the required structure:
  - `"method": "GET"`
  - `"_verb": "get"`
  - `"data"` field containing the filtered list of people

The response will be a JSON object with the filtered list of people over 50 years old from the UK, ESP, and US.
