This is the bi-weekly visible open thread. There are hidden threads every few days here. Post about anything you want, ask random questions, whatever. Also:

1. One reason I love you guys is that you always know useful information about random things. Some of the comments on pharmacological tolerance really helped me understand it better; particularly comment-of-the-week-worthy were Erebus, George Dawson, and Raza. Related: r/nootropics recently had a good thread about Adderall tolerance.

2. Important Consumer Warning: I was recently on vacation and tried to get some money out of a Bank of America ATM. The ATM took my card and refused to give it back. When I called the bank’s number, they just told me that this just happened randomly sometimes, they wouldn’t help me, there was nothing anyone could do, and I’d have to get a new card from my bank. While I was on the phone, a passer-by overheard and told me that they’d had the same problem, also with a Bank of America ATM. Needless to say this seriously complicated my vacation. I wish I had known not to use Bank of America ATMs at any point when it would be inconvenient to permanently lose the card involved, so now I am telling you.

3. Worth highlighting: the last open thread’s discussion on people who willed themseves into having their first childhood memory.
