Hey bud,
Did you know vaping causes you to crave a smoke and suffer withdrawal symptoms if you ignore the craving. Nicotine is also a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack. Heart attacks killed 365,914 people in 2017. Next time you take a puff of smoke remember that that could be your last days on earth.

fitness. For example there are endurance exercises that increase heart
rate like running or swimming. Other types of exercise include strength,
balance, and flexibility. These different exercises help improve a different aspect of someones health.
