Subject: ls -l  /proc/1/exe -> Permission denied

Trying to real /proc/<pid>/exe I noticed I could not read links not 
belonging to my user such as:
jocke >  ls -l /proc/1/exe
             ls: cannot read symbolic link /proc/1/exe: Permission denied

Is this expected?

uname -a
Linux gentoo-jocke 3.12.21
