Hi and thanks for your question.
States determine alimony/spousal support on a case by case basis and will first look to the need of the party requesting alimony and the ability to pay of the party from whom it's requested. I'm attaching a chart put out by the American Bar Association and from that you can see that most states have a list of factors that they will consider in determining the amount and the duration of alimony, if any. Most states claim they want to do what is "fair" -- so even if you meet or don't meet some of the factors, the court will look at your specific situation to determine what is fair.
Some things in your post jump out at me as factors a court of any state would consider, some in your favor and some not.
First, the fact that you've been married for 27 years means that you have a long term marriage and states will consider the length of your marriage in determining whether or not to award alimony. This may be a negative against you.
That being said, however, if you are close to retirement and/or you are going to be on disability because you cannot work, these are factors that would weigh in your favor that you would not have to pay alimony. The court should look to each party's earning capacity in determining whether there should be an award of alimony. If you are disabled, then you have no earning capacity.
This brings me to the next issue of your wife's earning capacity. You say she refuses to work. If she can work but is choosing not to, then she will have a difficult time arguing that she should be entitled to alimony. If there is nothing preventing her from working except her refusal to do so, the court should consider this and should not hold you accountable for supporting her when she should be self-supporting.
