I am looking for two papers. The first was published in 1988 (?) by a
researcher at Harvard who performed autopsies (biopsies?) on
marathoners' legs and found a proliferation of connective tissue he
termed 'microfibrosis'. I don't know the author's name.

The second paper was published from research at Mass General Hospital
in Boston where 1500 pain-free individuals were scanned with an MRI. 
1170 (?) of them had herniated or bulging discs. I think the paper was
published in the 90's, but I am not sure. I do not know the
authors'names.

I will pay $15 for each paper.

Thanks.
