It's nearing the point of do it now or die. You must begin and continue a multi day aerobic program. If you are in Lorain County join Splash Zone for $56.00 for 3 months to use the pool. Take your pack and use the stair climbers or treadmill with 35lbs inside. Belive me you must start ASAP and keep at it to survive the strenuous effects of high altitude.
