After i turned 30, i was rapidly confronted with consequences for my unhealthy lifestyle from my teens and twenties, you learn quickly that things need to change after glancing at death a couple times and at hospital stays.

Thankfully i have the motivation to keep living, and that began to drive my actions after that

Eat healthy less processed foods made in your kitchen and bought from farmers and markets

Gym and active hobbies like hiking and dancing at least three times a week

Hygene routines solidified, brushing teeth twice daily, non negotiable, thorough flossing and even tounge scrapping daily, fresh clean towel after the daily shower - its worth the extra laundry imo

Skincare, especially daily sunscreen, non negotiable - face, neck, and exposed arms - brimmed hat when on a daily walk, upf 50+ clothing if outside for more than an hour doing chores of on hobbies - in the morning vit c on the face, and in the night a retinol (vit a derivitive)

Hearing protection when at any music shows, wear them so you can keep hearing shows for the long term and not be that guy that says “WHAT?!” at every sentence. Genuinely, i prefer to go with good earplugs now than without

Keeping hold of and scheduling meets with friends, family, and neighbors - as you get older it gets so easy to drift a part, we are all busy, and that 3 minutes spent texting to say “hey lets hang out, does thursday evening work?” makes good friends into best friends - lonely people die faster - be that family, friends, neighbors, and yourself

As i get older and take care of myself, its easier to love myself, and thus, its easier to love other people and receive their love too. Get philosophical about it, it also takes care of you.
