I'd say staying up to date with vaccine may be the best bet in building resistance against diseases.

Having the habit of washing hand before and after eating is really important

Surely all but sleep routine is the hardest to keep to as we grow older :(

So many diseases spread because kids are not washing their hands

Not only because of covid 19 but good practice overall

I wish I applied more sunscreen when I was younger.

Washing hands first thing after coming back home.

Proper sleep routine keeps you fresh and healthy

Sleeping well is important for long-term health.

Dont touch things anyhow. Wash hands frequently.
