Luke 12: worries about aging

I am retired and getting older. There are many problems that comes with old age: sarcopenia (loss of muscles), difficulty in absorbing nutrients, lack of memory, etc. Everyday I go to the gym in order to age with quality of life. I read:

22-24 He continued this subject with his disciples. “Don’t fuss about what’s on the table at mealtimes or if the clothes in your closet are in fashion. There is far more to your inner life than the food you put in your stomach, more to your outer appearance than the clothes you hang on your body. Look at the ravens, free and unfettered, not tied down to a job description, carefree in the care of God. And you count far more.

There is more than gym and healthy food. Look to the old ravens. The Lord takes care of them too. In a way, too much worry about aging is futile. Certainly I am destined to get weaker and die some day, but I must remember that the Lord is with me in this process. He is taking care of me even when my body is aging. He is the Father that loves me and is very generous with me.
