Not just adults, but teenagers. Because of this, youngsters tend to also get heart disease too, despite the small age. According to cdc.gov, a family history of heart disease increases the rates, especially if one of your relatives got it under the age of 50.

Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.
