What can we do if we can't do anything?

I was writing a note about the importance of preserving health for old age. Because if in old age I cannot think or act, it will be very, very bad.
 
  • What will you be able to do in old age, even if you are incapable of most things? (I asked myself).
  • I must be able to love.
  • What else can you do?
  • I can believe and I can desire.
  • How are these things interconnected?
  • I don't know if it comes naturally, but it seems: Desire = Faith * Love.
  • How do you differentiate these words for yourself?
  • Love - it's love for a Person. Faith - it's love for God. Desire - it's the longing for Love and Faith to flourish eternally.
  • Aren't you confusing anything?
  • It seems I'm confusing everything, but let it be so.
  • And what do these reflections give you?
  • If we consider time and all the things we manage to do within this time, it's like an airstrip with flies that we enthusiastically and energetically launch in different directions, like tiny planes. It's important to attach seeds of eternity to these flies. So that more flies carry and sow the seeds of eternity: Love, Faith, and Desire.
