Would you like to know if your body is older or younger than it should be? Dr. David Wikenheiser has been studying aging in Vancouver, Canada, for the past 10 years and has found the average person is 15 or more years older biologically than their actual age.
He says: “We all know people who are 30 but look over 40, and others who are 70 yet look 50, the difference comes down to lifestyle. Some peoples’ bodies get ‘rusty(生锈)’ faster than others, and this makes them age more quickly.”
After conducting more than 3,000 tests, Dr. Wikenheiser believes that, on average, you can ower your biological age by 10 years in three months with the right lifestyle changes.
“You can’t change your genetics(遗传学) but you can make other changes such as eating the right food, drinking enough water to flush out toxins(毒素), exercising and managing stress,” he says. But exercising too much is just as bad as not doing enough. Working out for more than two hours at a time every day puts too great a strain on your heart.
