Healthy people dying is one of the outcomes of getting the flu...so I suppose it could be argued this is one way of getting over it.
The influenza virus does not discriminate when infecting someone...it doesn't discriminate against race, socioeconomic status, health, age etc. Some factors, such as one with a lung diease, can however have higher risks of complications from the virus. Very healthy individuals can also have similar complications, however the risks are lower (but are not zero).
Generally healthy individuals may cope/recover better from the influenza virus, however, a person's response to the virus can vary enormously due to a lot of factors outside their control, such as genetic disposition, health condition at the time of infection (say one already has a cold or other common unpreventable diease) and post infection contacts which can cause secondary diseases like pneumonia.
While the flu vaccination is not the magic bullet, it does reduce the risk of infection from the most virallent forms of the flu known at the start of the flu season.
If one thinks that getting healthy, eating healthy, raising your immunity... is the hest and only way to prepare for the winter flu season, this approach goes against well established medical and scientific evidence. The later evidence includes 'The administration of influenza vaccine is the single most important measure in preventing or attenuating influenza infection and preventing mortality.'
Believing being healthy is all one needs, is something that antivaccination supporters think prevent one getting many preventable diseases. Unfortunately past generations (before vaccinations were 'invented') possibly ate healthier (food was organic, fresh etc) and were possibly in many ways healthier than current generations, but this did not stop them being crippled or dying from these common, debilitating and (vaccination) preventable dieases.
Like @draughtrider outlined in another thread, I am concerned that you may have a hidden agenda or be in the 'health remedy' industry. It does not appear that you are impartial/have a balanced view to some of the discussion points in this topic.
