So we learn that the “update” command by default updates only 1 document, and you have to specify the “multiple” modifier, while the “remove” command by default deletes multiple documents, so you must specify 1 to prevent that. Do I still like MongoDB?

In this example if I want to delete the 2nd record of age 16 .then??
