+# Find the Oldest
+
+given an array of objects representing people with a birth and death year, return the oldest person.
+
+## Hints
+- You should return the whole person object, but the tests mostly just check to make sure the name is correct.
+- this can be done with a couple of chained array methods, or by using `reduce`.
+- One of the tests checks for people with no death-date.. use JavaScript's Date function to get their age as of today.
