I quit about 10 months ago after being diagnosed with Type II. Now I drink water with an occasional unsweet/diet iced tea.
I look back on that diagnosis as a blessing. I've dropped 30 lbs, changed my diet (Fuhrman's Eat to Live), more exercise. About a month ago, I went on vacation with my 11 YO son (mom stayed home), and came back with so many great memories.
The best memory was a day of canyoneering in Water Canyon, UT, near Zion NP. Our hike in was 2 1/2 miles with an elevation gain of over 1000 feet...damn near killed me (lol). On our way back, we rappelled 5 times, ranging from 40-90 feet.
My son wants to do it again next year, so I better stay in training. I'll add a stair-stepper to the mix.
Without the drastic change in lifestyle, I never would have attempted that adventure.
Yeah, I recently hiked 1 mile with the grandkids with an elevation gain of 880 feet. Seemed fairly steep (16-17%). Nearly killed me twice..in both directions (knees gave out on the way down). Beautiful scenery, though.
