I am now an Elder...willing to give advice...if anyone is listening. Whatever you do, don't get grumpy and don't be bitter. Stay light-hearted and playful...any thing else is a waste of time, a wasted life. Keep playing, keep laughing in your heart...did I already say that? Old folks repeat themselves. Alcohol, in moderation, is a good thing...helps deflate the seriousness of each day's issues. Don't be bitchin' at people around you. You can't change them for the better anyhow. You can only push them toward worse.
My 69th year is almost complete and I believe I am in a good place...moving well and playing with my new dog every single day. The wife gives me a hug and a kiss every morning and evening and she means it when she says, "I love you." I feel it throughout my being, when I say it back to her. Stay forever young and try to sing a new song every morning while you are brewing coffee. There are things to worry about but, I try to limit the 'worry time' to only a few minutes each day. Inflammation is a killer, try hard to avoid inflammation...Advil or Aleve is helpful here. Don't mix alcohol with your anti-inflammatories...bad for he liver and pancreas.
I'm thinking that after seven decades we can stop striving for perfection and cease being competitive. Actually, we could have given up on each of those things a couple of decades earlier. I don't shave every day and I don't look in the mirror more than once a day. There's no fixing or primping me now. "I yam what I yam..." I didn't come this far to make it un-fun.
