How is it possible for someone to live their life without any amount of stress?

Generally I don’t live, what we would call “under pressure” like having two jobs and being “on the run” without any amount of free-time, but I feel like I’m being “under pressure” by small things (for most people), like if I’m expecting a call from someone at 1:00 and it goes 1:15 and hasn’t called, I feel really stressed and anxious.

I don’t want to feel stressed, because stress makes you age quicker.
