Brussel sprouts used to be truly awful, made me literally wretch. Now I eagerly make and order them as a bar snack.
To be fair there are two reasons beyond my changing tastes for this. First, my mom liked to steam brussel sprouts whole and serve them with margarine, salt, and pepper, now I generally cold sear them or roast them in the oven with much better seasoning. Maybe even some bacon pieces and blue cheese mixed in. Second, brussel sprouts did actually change over time to get less bitter and awful since I was a kid.
Opposite. I wear wool socks. Sometimes my socks are sopping wet, but my feet feel dry.
