Hang out with the folks in biotech if you want to be inspired. You can literally see progress on a daily basis for a host of age related diseases ;)
You can also participate indirectly by tracking the market and making small investments in say: AbbVie, Gilead, Regeneron, Spark Therapeutics, Ginko Bioworks, etc. Or apply your skills to Kaggle style ML competitions, citizen science projects, open access gene banks, etc.
Stay positive!
