Alternatively, you could try one of the following fields:
- bioengineering
- biotechnology
- bioinformatics
- medical data engineer
- lab/ hospital equipment field service engineer
These would allow you to either directly or indirectly help patients become better or make people happy and tie both med and engineering together. Some, like the last one, are also travelling jobs e.g. you are paid to travel to different labs/ hospitals within the same state or interstate to fix their equipment and it’s still mostly a 9-5 job (apart from interstate travel).
If you want more direct jobs that might make people happy, related to your passion for boxing, and maybe please your parents (close to medicine and are typically secure jobs) you could try these:
- physiotherapy
- occupational therapy
- physical therapy
- radiography/ sonography
These don’t usually need UCAT, from memory, but might have other prereqs and are typically reliable 9-5 jobs, which then leaves you free time after. However, the salary may be lower than doctors or engineers.
I’ve tried to think of a job that would satisfy all your passions and requirements, while also mixing med and engineering, but it would be very niche and difficult without experience first.
