You will have to find a different solution to the problem. To machine precision, that matrix looks singular. This usually indicates that it's not the right matrix to try to invert.
It might be a scaling issue though: If you're measuring age in days and hormone concentrations in Molar, then you'll get that sort of eigenvalue ratios in a fairly benign way.
