No. This returns the persons age. You want the index, so you'll have to do this in 2 steps. See the documentation for max to see how to get the index of the max value.

One thing to be aware of: if there are multiple people with max age, this will return the first one only. You can use logical indexing to extract all entries that match your condition
name(age==max(age)).
