There are special halachos on how to treat a yosom and almana. Do they equally apply to an alman? And do they apply regardless of age? IOW, do the halachos apply whether it is a 12 year old yosom, 22 year old or a 92 year old yosom or almana?
And, as a practical matter today, how should one treat a yosom and almana differently than a non-yosom or almana?
The laws of how to treat a an orphan and a widow are not really limited to them. The reason the Torah specifies the orphan and the widow is simply because those are the people who, having no one to protect them, are often subject to abuse more than others. But in truth, abuse is wrong no matter who it is directed at, regardless of age, gender, or marital status.
