When it comes to being healthy it feels like people focus far too much on the small details rather than health as a whole thing. The same goes with exercise... really whether you do 10 or 15 reps really doesn't matter unless you have a serious goal with training or whether you do bicep curls before triceps push downs or vice versa. The small details really don't matter when it comes to working out, it's more that you do it and have fun. Not to mention that health isn't about whether you do 25 minutes of walking or 28 minutes of walking. Whether you manage to do 8 burpees or 10 burpees, exercise is exercise and you should enjoy it.... and doing it regularly in some form is better than thinking you had a bad workout because you just managed to run 20 minutes and not 25 etc .
Health is a broad thing and not so much about the small details. Micromanaging and counting every gram of food or every macro or micronutrient isn't necessary. Health isn't about whether you eat 250g of carbs or 260g. Getting stuck in the small details isn't necessary and if anything can make you more sick.
See health as a whole. About happiness, feeling energetic, capable of living life and doing what you want to do. Free from pain. Mental health and social health. Taking care of yourself and nourishing yourself properly, but also regular activity if that is what makes you healthy at that stage in life. (For example if someone has a virus then exercise might just make them more unhealthy and so not actually benefit them, just like if you are underweight then doing a bunch of cardio would not be healthy even if cardio might be healthy for someone else.)
Focus on what is healthy for you and don't focus on small details. Instead ask yourself what makes you happy and healthy? Health is more than food or exercise or weight or appearance, health is a whole body and feeling!
