It's not at all hard to believe. All the people in my family, for instance, have changed grocery habits and stopped discretionary shopping in stores essentially entirely. Why? Many are older and have risks yet also have full lives and want to live to play with their grandkids. We prioritized gathering with each other cautiously over spending money shopping and changed habits immediately (I started working from home March 12, before any US guidance).

Sweden is an interesting example. Comparing Sweden and Finland, for instance, older people essentially cloistered themselves in Sweden because they had no trust that they'd be safe in society, and their spending dropped by a higher amount than old people in Finland, who changed their habits less due to the swift and more stringent government response? My old-person family members in Finland were able to keep shopping, going to church, and having birthday parties with many families due to that response (as opposed to in the US where we limited ourselves to gatherings with max 3 households and did everything masked or outdoors due to several people still working on site).

Perhaps you live in a very different place. You certainly interpret statistics quite differently given your example of Florida.
