Working part-time in old age is a good idea so long as you enjoy what you do. People who work live longer (god forbid) healthier lives. I plan to work, at least in some capacity, until I die.
Traditional retirement was made for an industrial age where people’s bodies were exhausted from a lifetime of physical labor. There’s no reason to retire anymore.
My dad is 78 and I convinced him to go back to grad school rather than staying idle at home. Elderly people need to exercise their minds in order to avoid Alzheimers disease.
