Everybody is posting positive things that has impacted their bodies. I think I will share something different.
I have been doing martial arts for 35 years. About twenty years ago I was introduced to a man named Saito Sensei. He did Aikido but in the demo I saw him in he showed karate and aikido. He was very powerful and moved very well. A few years ago I saw that he was going to do a seminar and I thought I would go see him again. What a difference twenty years make. He could hardly walk. I realized something, all the martial arts I had been doing was useless because my real enemy was not another man but time. Time is what's going to kill me. So now that I am fifty I would have to say that the thing that has impacted my body the most is time.
Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.
Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.
Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.
Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.
Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.
And you, my father, there on the sad height,
Curse, bless me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.
