Go for follow up. My friend cycled alot, hardcore also. Now at home, last 2 month have heart attack 2 stent deployed. You, 5km is peanut. You want to wait until have heart attack up to you.

When I knew him already jaga makan one. Younger life don't know. Cycling from Perlis to Penang. Going uphill downhill road. Blood pressure most of time normal. No meds require before this.

If that is how you eat, start control la. Someone control and exercise also kena already.

I suspect never check, don't want to ask him at this moment. I think before this got indication blood pressure high that is why he started cycling. Il someone ask for advice I always say don't stress your heart. Especially if after 35. Just do casual exercise. Different story if doing it when still young. We heard alot of story died during exercise or active kind of person.

That is why lot of people got problem only want to start exercise. Heart already not optimum but doing stressful exercise. Just overworking own heart. That is why know ownself don't do what healthy people do straight away. They been doing while their body don't have problem.

Heart attack.
