A breathalyzer or breathalyser (a portmanteau of breath and analyzer/analyser) is a device for estimating blood alcohol content (BAC) from a breath sample. Breathalyzer is the brand name for the instrument that tests the alcohol level developed by inventor Robert Frank Borkenstein. It was registered as a trademark on May 13, 1954, but many people use the term to refer to any generic device for estimating blood alcohol content.
The deadline to file your federal taxes is coming up, and this year Americans will spend more than 7 billion hours preparing their taxes and will hand over more than four trillion dollars to federal, state and local governments.
Another 8.3 percent choose to file with the help of brick-and-mortar tax companies like H&R Block. Looking at these two groups together shows that 36.8 percent of Americans prefer to hire a tax preparer to file their returns, which means most people prefer to hand this chore off to a paid professional.
