I'm going skying next week and it's been seven years since the last time I did that. Do you have any advice ?

Is skying sky diving or something else? I never heard of it. Also, you never really forget how to do something. It's like riding a bike, you never forget that. I am sure once you get back in the surroundings you will be reminded of what you need to do. Just relax and let it come back to you.

Yup.

Try to avoid falling over, whilst skiing (yes, I knew what you meant). It can be painful.
