This endpoint filters the `people` list to only include those whose `age` is greater than 50, and returns that filtered list in the response data under the `data` key. It also includes the requested `method` and `_verb` metadata fields.

The `if request.method != "GET"` line checks if the incoming request method is not GET, and if so, raises a 405 Method Not Allowed error per the requirements.
