Your body keeps changing throughout your life.
Most drastic changes occur during puberty, and then around 40-45, and then some more in the 60s.
Between 20-30 you're still going through hormonal changes and don't really reach adulthood until about 25, where then you level off and remain
fairly static for about a decade.
Changes in environment, sexual activity, partners, diet, work routine, exercise, and even wealth or lack of it can effect your physiology.
Other more subtle effects than can cause drastic side effects involves what you do with your brain. If you occupy yourself with free-time activities
that involve spooky things, for instance, your subconscious will gnaw on that stuff and trigger sympathetic responses like irrational fear for no
reason because you've been dwelling on that kind of material, even if consciously it really doesn't scare you or freak you out at all, the deeper
subconscious can and will run with it all sorts of ways.
