I can safely say that I won't be doing any of this over the coming season (even though I was mildly into extreme skiing in the late 80s to mid-90s) as:
I will soon be 55 years old
I have two severely damaged knees, had to give up running in my mid-30s and skiing will be the last thing I give up.
I lack the ability!
This kid is 12 years old!!!
If only we lived in a country with seasons. I wonder what his mother thinks of it.
