The file's directory entry contains a hard link (or pointer) to the inode for the file, so every entry listed should have at least one hard link.

A hard link is a directory entry that points to an inode, while a soft link or symbolic link is a directory entry that points to an inode that provides the name of another directory entry.

Every once while you see a swimmer take it up and then in, it is really hard to transfer that momentum from a steep angle entry to a horizontal speed.
