I'm constantly battling age. It started at 25. At 25 all your cells hit G0 and you are officially an adult organism. Any damage from then on out is typically permanent, scar tissue.
So I'm coming up on 30 and still have nicer skin than alot of younger 20's people because I don't drink much, drink herbal teas, haven't had trans fat in appreciable amounts since I was 18, etc. etc. I keep a pretty strict diet. Not alot of meat. Mostly rice, eggs, sometimes chicken. Vegetables, carrots, corn, that kind of thing.
Age is definitely just a number. I see 40 year olds who look like they should be casket shopping and I see fit 50 year olds. You have to take care of yourself.
And thats the thing... the older I get the larger and larger chunk of my time is dedicated to taking care of myself. I feel like its getting ridiculous at 29. So I can't imagine. But then again I hiked 6 miles and only got sore legs like I'm a teen. Health is definitely something valuable to me. I have yet to run into an obstacle that I just cannot overcome because of age.
Its the little things though, chapped lips taking forever to heal.
I really lament getting older. From 25 on out, it is nothing but loss. Ahh the good old days of being able to lift my arm above the shoulder.
I really hope that is never me.
