Just really quickly, because posts like this make some people feel awkward: multiple sclerosis is terrible. Like last year, I’m doing a charity bike ride to raise funds to fight MS, and I welcome your donations. I promised a bunch of stuff to donors last year, and I repeat those promises now (and if I didn’t follow through with any of you last year, let me know and I’ll make amends). So, give some money if you can – here’s the link. It will make you feel quite a bit better about yourself.
