Advantages of microscopy as a hobby
The advantages are, naturally, subjective, but might include:
Hobby at home: You do not need to go anywhere. All you need is a desk at home
Not much time needed: Turning the microscope on to observe a few specimens can be done quickly and you do not need to go anywhere with your car.
Take along: the possibility to take the hobby along as you go traveling (using portable microscopes), if you are interested in natural observation of the country you visit. I have never done that but know of a few people who do this. I would worry too much about the scope becoming damaged.
Weather: you are not dependent on good weather
Personalization: There are several sub-branches of amateur microscopy: observation, collection of slides, collection of vintage microscopes, photography
Easy to start: You can teach the basics of microscopy yourself. The entry barrier into the hobby is not high. The costs are not high and it is not a complicated hobby
Specialization: you have the possibility to specialize and to become an expert in a specific branch of light microscopy.
Independence: You are not dependent on others to do the hobby. If you want to play a competitive sport, then you have to agree on an appointment to meet each other.
