Ski gave me more pain than any other sports, but no matter how much I complained, I was always attracted back, magically.
Not kidding, ski is probably the sport which gave me the most pain, not because of falling down (I was too slow to feel pain when falling), but because of the sore muscle and painful knee suffering from the pressure. Every time after ski, I felt my whole body was broken apart, every piece of my body was screaming and complaining how much they hated ski. No need to mention how “user-unfriendly” this sport is: strict requirements for the weather and geology, thus every year when I restarted this sport I was nervous how much I still remembered from the last year. Oh also the cost for the equipments (rental or purchase) and entrances to the ski resorts are very expensive.
