Is there a demand on only fans for a early 40s, BMI ~30, balding, male?
I can touch my toes to my nose…
If there is…..   I mean….   I would do it….
Otherwise I did come up with a side hustle that I love doing.  My son and I manually clean garbage cans on a quarterly basis for people in our city.  Essentially, I rigged my pickup to latch on a huge water tank, I fill it up, and attach my power washer to it.  We stick the empty can upside down to hose it out bigtime - then I add a few cups of liquid soap - brush it out - rinse again - and boom its done (takes about 15 minutes for 2 cans tops, 5 extra per can).  We currently have 47 quarterly accounts and collect 20 dollars per completion for 2 cans.  All of the homes requesting the service are in my own neighborhood and are within 5 minute drive.  Also - we instruct them to leave the cans they want clean at the edge of their driveway for efficient work.
There is a massive demand for this and everyone that is approached I an established neighborhood wants this service.
Other than this I do a lot of swing trading and investing
