No, it's not the flu as the symptoms are quite a bit different: heart, lungs, joints, beady little eyeballs and then hock up globs last on the list. I sold a stereo amplifier, waked fairly rapidly up a ramp and some steps with it and I just had to freeze in place for a few minutes as my heart was going berserk. That's not the flu.
Life seems to be work, sleep, play guitar, buy stereo gear, repeat.
A yanked tooth shouldn't bleed for long at all, you'd better get with the doctor about that one.
