That's partly why I have a lot of reservations about all the "how to get boosted" stories we keep seeing. There are so many variables! Some of those tips can really lead you astray.
BTW I went to a birthday dinner tonight at Dauphin, that top-floor restaurant in downtown Mobile. First time I've been eye-to-eye with the top of the RSA building during a meal (until fog defenestrated it). Apparently the Mobile fire codes don't allow candles, and they stuck an edible "birthday medallion" on the cake instead. Delicious!
