I started wearing a mask in crowded public places in about 2020 (for some inexplicable reason). I never stopped. I wear one in the metro. On buses. In crowded shopping malls (or even crowded small shops).

I used to get several colds per years and maybe one thing that caused me a fever each year (usually a flu).

I haven’t had a cold or flu or any kind of fever-inducing infection since … oh … call it 2020.

I rarely get sick, but I’m not going to speculate why, and I wouldn’t recommend taking advice from a thread like this. You can’t really know all the mechanisms behind why you get sick or not. There are people who smoke two packs a day and are rarely sick, and I’m sure some of them attribute that to smoking.

Avoid children

In my case, it’s probably like that George Carlin bit about swimming in the Hudson. I am not a neat freak. I eat things I drop on the ground. Etc. It’s like constantly vaccinating yourself against everything.

5 second rule can be stretched

Eat local honey

Be lucky and have a good immune system

Until last year i rarely got sick, “rarely” meaning maybe once a year and then only lightly. Since october/november last year i suddenly started getting sick almost once every month without any significant changes to any of the following:

• Social contact
• Diet
• Workout
• Sun/Outside time
• Happiness

Im the wrong person to ask for this obviously, because im still trying to figure out why im getting sick all of a sudden. The things i mentioned are probably still all valid factors tho.

Being an introvert and maintaining a healthy diet.

• don’t share food

• wash hands but avoid antibacterial soap

• get enough sleep

• Avoid drugs (e.g. marijuana, alcohol, tobacco, caffeine)
• Get enough sleep (i.e. wake up naturally; no alarms)
• Regular exercise (primarily playing sports)
• Eat healthily (avoid sugar, avoid starchy food, eat lots of fatty meat and eggs)
