Uh, this code is from the Sam's Teach Yourself C Programming in 21 days and it never stops, what exactly is wrong with it?

Code:
#include <stdio.h>

int count;

int main(void)
{
	
	
	for(count=1; 1<=20; count++)
		
                printf("%d\n",count);

	return 0;
}
I have no idea why it won't stop and I know this is simple I was just trying to refresh the stuff about loops but this is confusing...
