I'll continue to hold onto stocks like AAPL - I invest for the long term so whatever happens over a few years doesn't worry me too much as I still have faith in the company
when I'm closer to retirement or retired I wouldn't want excessive volatility as I wouldn't have the time to ride it out, so yes I'd hold more cash as I approach that age
I'd pick Tohru from the anime series Kobayashi-san Chi no Maid Dragon as she's (usually) a friendly, cheerful and hard working dragon who can take a human form.
