I'm Irish and never heard of someone getting one unless they were checking for something specific. However, I do know that regular health checks are recommended once you hit 45 or so. Not sure if that includes blood tests.
We're currently ranked 16th in the world for longevity, so I doubt regular blood checks is that important - at least, I remember reading previously that there's no evidence regular blood checks are actually useful unless you have an ongoing condition.
Irish too, and I get bloods done every year because I noticed my health insurance covers me for an annual checkup. First time I got them done revealed I had very high cholesterol
