The big push for Christmas and the New Year festivities are over and January may feel a little flat, if not around the mid-riff. It’s cold outside so all the more tempting to keep that front door firmly shut. Those a little more daring will be rewarded for embracing the spirit. There’s something special about feeling cold air on your face while the rest of you is, hopefully, warm, tilting your face slightly upwards and taking a deep breath of crisp, cold air, your lungs tingling with mixed delight and shock.
