Far from being DEmotivational... This thread and the memes posted are actually kick-ass and inspirational.
Ditto to everything everyone said here. About 'fighting' aging... It completely boils down to how well you maintain your physical and psychological health. Many older folks get depressed due to increasing isolation as loved ones and friends begin to die off and they simply stop giving a fuck about their own self-maintenance. Chronic illnesses, infections, and weight gain/crippling disabilities often follow very shortly afterward.
The key to keeping one's strength and ability to live independently even in advanced age is to NOT give in to the resignation demons. I know I will shoot any motherfucker who tries to take what I have rightfully earned. No way in hell will I give up the health that I have now to resignation, barring external and uncontrollable factors such as serious, unpredictable illness or debilitating injury. Staying active, getting a side job, and EATING RIGHT are just some of the things you have to do to stay in shape. For years now, I ALWAYS have two red apples each day, skin and all, right down to the core. A handful of walnuts is also the norm. Green leafy vegetables and tofu is another staple I literally live by. A diet rich in pectins (natural cholesterol and clot reducers) and antioxidants are 3/4ths of the battle. I am 32, but I never stop thinking about the challenges me and my family may potentially face down the road.
Stay safe and healthy out there folks...
