st: row means for at least 10 observations greater than 0

I need to take an average of several variables in a row, but I want to average of the row only if there are at least 10 variables without 0 as their observation. The data looks like this:
PersonID 1990 1991 1992 1993 1994 1995 etc...
1 0 0 3 3 5 6
2 1 1 5 3 0 7
3 1 1 2 1 4 3
4 0 0 0 0 5 5
does anyone have an idea how to do this? I've tried egen and rowmean() but I am not sure how to code for if a row has more at least 10 observations > 0
Thanks,
Nick
