There is a difference between being a workaholic and someone who works a lot because they have to.
Example:
Last summer I worked 55+ hours/week between two jobs in order to buy a real bass rig and some other things. Most of the time I am very lazy. But I'll be pulling as many hours /week as possible with one job this summer in order to afford a new (used) car.
On the other hand, my grandmother is nearly 80 years old, yet she never sits still. She does clothing alterations, cooks, cleans, organizes, shops, gardens, takes care of her dog, whatever.
