I am 52. I bill out consulting doing data science (stats, data wrangling, algorithms for weighted fusion of data into a single source of truth). On my own projects I combine my customer and market research background with web development (self-taught in the past 3 years). I have also maintained an interest in and developed techniques for automating text analysis in the last 15 years. Technical life doesn't have to be over at 30 or 40. Just keep experimenting and learning.
