If you want to stay fit into old age, you should start training early. Smoking, obesity, alcohol and too much stress should be avoided.
Regular exercise can slow down the aging process. Eating without trans fats can release inflammatory factors throughout the body and thus also in the brain. Regular relaxation and, above all, sufficient sleep play a major role in general well-being. The brain also benefits from the relaxation phases. Too little sleep and poor sleep quality are associated with cardiovascular problems and Alzheimer's.
