unless you are willing to pay $ 35.00 ‐65.00 dollars per article.

It is likely that your institution’s library has facilitated link‐out in PubMed to link you
directly to articles from journals to which they subscribe to.
It is also likely that your institution’s library has an Inter‐Library Loan service that will
“borrow” the article you want from another library for you for a small charge (certainly
less then $35.00!) or for free.
Contact your librarian and find out what services are available and how to use them.
