I'm in my 30's doing marketing and am starting to feel like the old man of the teams I work with.Ha Ha, you'd be a baby on my team. I'm 61, on a team of 20 people in a department of 100 people. Age range 21 to 72. I find little or no correlation between age and anything that really matters. Like quality of work, deliverance of value, or wanting to be on the same team.
I look around and there is hardly anyone over 40 and no-one 50+ unless they hit executive level.
That's just where you're at. I know hundreds of people in their 50s and 60s doing great work who are not executives. Lots of them are programmers, too. The happiest and most successful are doing stuff they love (or have learned to love).
The industry is about new technology and working
No. Any industry is about satisfying customers. Don't confuse what's in front of your face every day with what really matters.
..so as someone that likes to plan ahead. What do you think are good career options for the 50+?
Exactly the same as for 49-. Whatever's best for you. (More below)
I've been trying to think of jobs were age is an advantage.
I can't think of a single job where age would be an advantage. Experience maybe, but not age. I can think of a few where it would be a disadvantage: pro basketball player is one. But that belies the point: You should be thinking about a job where what you bring is an advantage: your skills, education, passion, etc. Forget age and focus on this.
The best I can think of is financial planning. Most people visit their planner when retirement is on their mind, so you'll likely be meeting people of a similar group and mindset.
Not sure I understand what you're trying to say here. If you love financial planning, by all means do it. But if you don't, finding a reason to do it doesn't make any sense. You're unlikely to find much success in any field you don't love, no matter what the other co-factors are.
Whereas in this industry being 21 and enthusiastic wont go far with many older people.
Oh yes it does! I have 18 people on my team under age 26 and I love working with them!
What does HN think are good options?
I don't know what the rest of HN thinks, but here's what I think:
Find what you love, what you're good at, and what puts food on the table and do it! Pour your heart and soul into it, get better at it, and it would be hard for you to NOT make the world a better place by doing it. Forget the rest, what others think, what's trendy, what you think may be important (but probably isn't).
I've been programming professionally for 38 years and can't imagine doing anything else. I hope I go another 38, no matter where the industry takes me.
My best advice of all: Take care of yourself now or you may not be able to do much of anything in your 50s.
