Memory eraser drugs
Here's something I recently learned about and find both fascinating and terrifying:
Midazolam is a benzodiazepine with antianxiety and sedative effects. Because of rapid onset and short duration of action, it is commonly used in diagnostic and therapeutic procedures to create anterograde amnesia, which prevents undesirable memory of the procedure that is painful for the patient.
There's a whole class of drugs that have this effect.  I always thought anesthesia drugs just sort of put you to sleep.  I didn't realize they actively prevent your brain from forming new memories. #science

Why keep blogging
Every few weeks or months, I think I've reached the end of "the things I want to write on the internet."  And then I come up with something else.  This part of me just doesn't seem to want to die. 

And I think I keep coming back to it -- and have kept at it for so long -- because it benefits me.  It helps me clear up mental clutter.  I like to think of it like this:  My brain is like a messy office; papers strewn about, post-it notes stuck on the walls, doodles on the whiteboard.  Blogging is like taking all that random, disordered stuff and putting it in nice neat stacks and filing it away.  Is it all gold?  No.  Does organizing actually accomplish anything?  Maybe, maybe not.  But going through the process feels like cleaning my brain.  I'm able to consolidate some disparate ideas, put together a coherent thing (sometimes), and free up space for more random brain activity.  I'm gonna keep doing it. #psychology

There should be a button in your car that lowers all the windows about an inch, so you can press it as you park your car in the hot sun and want to let a little air in but don't want anyone to be able to fit their arm in to unlock your door.
