Whether your question is about exercise, eating, or general wellness, post it below and we’ll put a selection to our panel on the night

There’s no bad time to take a more active interest in your health, but the new year, for lots of us, feels like a fresh start. Maybe you’re planning to sign up for a 10k or finally have a go at bouldering, eat a bit better or learn to swing a kettlebell. Maybe you want to keep up with your grandkids — or just be a little bit more physically prepared for whatever life throws at you.

To help things along, Guardian Live invites you to a special event with public health expert Devi Sridhar, journalist and author Mariella Frostrup, and health and fitness columnist Joel Snape. They’ll be joining the Guardian’s Today in Focus presenter Annie Kelly to discuss simple, actionable ways to stay fit and healthy as you move through the second half of life: whether that means staying strong and mobile or stressing less and sleeping better.

We’d like to hear from people in Venezuela, as well as from neighbouring countries mentioned by the Trump administration, about how they are responding to recent US actions

As Donald Trump prepares to make his first public appearance since Venezuela’s former president, Nicolás Maduro, and his wife, Cilia Flores, appeared in a US court and pleaded not guilty to all charges, there is growing international concern over the shock US military operation in Venezuela, which the UN human rights office has said undermined a fundamental principle of international law.

We would like to hear from Venezuelans, both in the country and abroad, about how you are feeling in the wake of these events – either positively or negatively – and what concerns or hopes you have for Venezuela’s future. You might want to share how this is affecting you personally, your family, or people you know on the ground.
