So Forty is the new thirty. etc., etc. Don’t believe it.
As one get’s older one’s systems are competing to do one in. Your arterial vessels become less elastic as does your skin. Those wrinkles in your skin show you daily how one system is aging. All the surgical stretching in the world won’t change the skins desire to deteriorate.
Other systems are diminishing. The kidneys age and filter less readily. The brain loses cognition that may start as early as forty. The lung function diminishes. The discs in the spine begin to age at about twenty one.
Knowing this is true I monitor at the allowed Medicare frequency the condition of those systems. The more slowly one’s systems can possibly age the better. I do all I can with diet and moderate exercise to stem the tide. Nonetheless the resistance training can injure the musculoskeletal system with repetition. In other words it is a balance of risks and benefits, generally.
Everything I can think of I apply to diminishing my intensity: reading, writing, word games, travel, stretching, etc. At a minimum it increases the quality of the life that remains for me at 74.
Loving God and others is central to meaning in my life. It involves emotional growth without which my personality would deteriorate as well.
May God bless all of your efforts to make this life a good and fruitful one.
