I think you calculated 85 months, not years, which are almost exactly 7 years.

Does anyone else use the .LOG feature?

Put .LOG at the beginning of a text file. When opened in Notepad, you should get a date & time stamp.

Open filename.txt, type something, save and close.

Now you have a journal for system and config changes, document collections, time entries, client visits, whatever. Has worked on every Windows box I ever had to use.

I use web browsers with tutamail and it works well.

Find your half life by eating this? Even though only 2.4% of the "original flavour" remains, consuming that tube will shorten your life as well.
