I'm 68 years old, retired. Former Ultrarunner, but then suddenly "whacked" with severe inflammatory arthritis and had FIVE total knee replacements in 10 years..end of Ultrarunning. Now do Power walking and distance biking. Currently undergoing assessment for some "neurological issues" (30+ lesions in brain, balance issues, numbness and weakness in arms and hands, fatigue, etc). After MUCH testing, still no diagnosis except "Medical Mystery".... SO helpful---and frustrating!!! BUT I adhere to the Never, Never, NEVER Give Up mantra and keep pushing forward and being a Badass. Working my way around or through my " medical issues " and putting it out there to show people the "mind over matter" DOES work...She believed she could...so she did...
