I'll tell you one thing for sure... I sure remember every damn migraine.

what good timeing my sister has just spent the day at hospital.diognosed with migraines she thought she was having a stroke.not always a head ache pain

Some memories are like the effects of fine sandpaper, overshadowed by further, and coarser memories. Migraines are like a Grinder.
You can ignore the worries of the world, but you can't ignore a Migraine.
