simple reg ex matching

[itshardtogetone]

Hi,
The value of $_ is 62. In the script below, I just wonder why the default 
variable match the number 6. What I wanted to say is that if the default 
variable $_ holding the value of 62, if match the number 6, then print Yes 
match. So what is the right way to right.
Thanks

use strict;
use warnings;

my $_ = 62;

if( $_ =~ /6/){
 print "Yes match \n";
}else{print "no"};
