52 days as of today and counting (somewhere between 60 and 65 this year, over 50 the last couple). I teach on-line, generally between the hours of 9 pm to 2 am as a .5 gig, I also have another .5 which is mostly afternoon and early evening meetings (although there are also full day meetings that take up most of my Saturdays and another 3 or 4 days a month). What have I given up for skiing? TV (aside from about 4 shows that I can tape and work in around the edges). I also don't do a lot of partying, since I have to either get back to town for meetings or go on-line. Having a six month season and Sunshine within 75 minutes drive helps as well (75 minutes could be a one-way commute in Calgary on only a moderately bad day).
I'm just finishing a 12 day, 6 resort road trip (timed to the school break). If you ski every day when you have the chance you'll find it adds up. I'll be retiring sometime in the next year or so, so I look at this as trying out a lifestyle for the next ten or fifteen years (then I may go back to nordic).
Just to add a health note: my doctor is really happy when ski season rolls around. She notes that it drops my blood pressure about 15 points. If I could just figure out how to make it a medical deduction
