How does an infinite life makes living boring?

Theoretical/imagined infinite life, that is. But you wouldn’t value the moments. You’d forever put things off. Really! Would you? You would be born and then your tissue would start multiplying. You would grow to your full stature, growth would stop. Everything would be same except senescence. Cells, tissue and organs would not show signs of aging and deterioration. Body would replace cells constantly, young cells. You still would have to eat, drink, pay bills and taxes. You could still die of natural causes. You would still have a body made of organic matter and bones that could still break and shatter if they encounter violent forces. You would still have needs that need to be met. You would have to work or no money. Infinite natural life would not mean an infinite money and resources to live off. You would still get sick, viruses, bacteria and such stuff still being around. Your cells and tissue would not age. You would still need sleep, still get tired, stressed, depressed. You would still live 1 minute, 1 hour, 1 day at a time, as you do now.
