People who studied Engineering are Engineering students/graduates, they earn the “Engineer” title by doing actual Engineering 😁
Discussion
If you graduate in engineering and not doing engineering you are engineer too..
It can be a bad example i give.
If you study longevity you need to reach 100 + years to be a expert?
Nonsense
If you successfully complete an Engineering program, you obtain the designation of an Engineering graduate. However, only by entering the field of Engineering and actively performing tasks can you truly earn the title of an Engineer.
Titles are not bestowed without merit.
In a similar vein, I believe that the field of longevity should use the term “researcher” instead of “expert”, given its ongoing development and relatively limited scope of research.
