Embrace the ice
Expose yourself to the elements and be a Wild Wednesday Enthusiast today. You might be in an extreme winter or a heatwave summer and if so you have the best chance to get into it - and enjoy the chill or burn, if just for a while - test your endurance (not your life expectancy). Walk in the rain - without an umbrella - sweat it out in the heat, roll in the snow, sail in a storm... if the weather is mild, you might need to be a bit more creative - find a sauna, perhaps do that hot yoga class I recommended here, have drinks at an ice bar - but don't wear the winter woollies they provide. It's all about going beyond your comfort zone. Find your zone, and then take a step outside.
