I'm 64 and in a senior developer role. I don't think resources are age specific. Their relevance is based on what level of experience you have, i.e. junior, senior, etc, what kind of development you do, front-end, backend, etc, what industry you work in and what kind of future work you are interested in. A community would be nice. I can share that I don't have the energy and endurance I used to have. Working long hours for a deadline has a higher personal cost. I'm not as quick but I have good judgement and I have more patience.
