It depends. Actually I've seen both sides of that scenario. As a former nurse, I've seen individuals so sick, it appeared that they were about to take their last breath at any moment; but the next visit I made with them they are sitting up in bed eatting and talking.
On the opposite end of that scenario, once upon a time I experienced one problem after another. My washing machine and dryer broke almost at the same time; A short time later I needed both a new stove and refridgerator...also a dish washer. I kid you not! All of these things happened about the same time. I believe it was because they were all purchased around the same time when I bought the house. at that time I'd been living in the house for about 12 years.
If you are speaking about finance, usually as soon as you get one problemn solved, up pops another one. You can almost depend upon that.
