what do you think can change in our lifestlye,from the cuase of the genetic breakthrough in the next 50 years.

Answer 1

Genetic therapy to correct inherited diseases as well as spontaneous mutations (as in some cancers) may be decades away, but should be well under way in 50 years. Selective enhancement of favorable traits (taller, stronger, attractiveness, etc.) is probably much further out due to many interacting genetic pathways that would require simultaneous tinkering.

Answer 2

The biggest breakthrough will be the appreciation that lifestyle factors are the major determinant of clinical expressions of variations in the genome. In other words, phenotype is the product of genotype + ENVIRONMENT. Environment is the dominant factor.

This principle is understood by many basic science researchers, but it is not generally appreciated by mainstream physicians or the media. The 'fifty-year rule' in medicine suggests it will be mid-century before this basic science concept becomes known and accepted.
