Risk, for a person, is less a number and more a question: could you watch your money fall by a third and not sell at the bottom?
A mix that looks fine on paper is wrong for you if a real fall would make you sell in a panic. The right amount of risk is the amount you can actually sit through.
A mostly-shares portfolio can fall 30% or more in a bad year. A mostly-bonds one usually falls less, though in 2022, when rates jumped, it fell about 17%. It also grows slower over decades. Picking between them means picking the fall you could sit through.
Answering this question calmly, before any money moves, gives a very different answer than answering it mid-crash. A limit set during a fall is usually the wrong one.
Work out −30% on your own money today, while calm, and write down whether you could actually sit through it.
