Back in the 90s, I had a job teaching MS Office to people. One class I was hired for was to teach a bunch of local judges how to use Word.
While discussing how to change fonts, one of the judges says, "Huh! Anal font, what the hell is an ANAL font!"
Maybe it is the same judge!
This is a bit involved, but will work if you have the time and know how to set it up.
You can likely port your landline number to a VOIP service and then setup asterisk. Use IVR to play a message when you are called. Have a code that your friends and family know that will allow them to break out of the IVR and ring an extention.. Funnel everything else to voicemail or whatever you want.. You will only get a ring when it is someone who knows the code.
I smoked for years, and could never quit.
Three years ago, I tried an ecig on a lark, and actually quit smoking without intending to, which to me seems like a miracle!
I went through a month or two of coughing up stuff from my lungs, but I never felt the need to smoke cigarettes.
I still have a nicotine addiction, but have been slowly weaning myself down to weaker and weaker e-juice. On day I will quit, but I feel a hell of a lot better than I did when I was smoking!
For me, the patch isn't even close !
The main contributing factor to fiber being inexpensive is that most lines are run above ground here in Tokyo.
NTT has a monopoly on Fiber. I haven't researched this, but I would be shocked if Sony wasn't riding on NTT fiber.
I don't have a motivation to change though. I have a 200/200 capable fiber line (realistically I get 60 to 70 up and down), and bandwidth is never a limiting factor for me.
