I hope this isn't too off-topic...
I went to the dentist today. It's the first time in 20 years. I was partially inspired to do this by Neil, who had to have "dental clearance" for his upcoming surgery. That caused me to remember a news article about poor dental hygiene being linked to heart disease. Apparently the bacteria that can take up residence in your mouth cause issues elsewhere too.
Anyway, I have periodontitis. I have no dental insurance, so this will cost me about $700. I also need a crown and a couple of fillings so I figure another $1500 later in the year.
I could buy a nice bike for the money I'm going to spend on my teeth.
